4. Rank the following from lowest number of particles to highest. Explain your reasoning.
2.3 mol H2O 3.5 mol H2 0.50 mol C100H202

Answers

Answer:

1. The molar mass of copper is 63.55 g/mol. To find the number of moles of copper in 5.00 grams, we divide the given mass by the molar mass:

5.00 g Cu / (63.55 g/mol Cu) = 0.0787 mol Cu

Therefore, there are 0.0787 moles of copper in 5.00 grams of copper wire.

2. The molar mass of glycine (C2H5O2N) is:

12.01 g/mol (C) + 1.01 g/mol (H) x 5 + 16.00 g/mol (O) x 2 + 14.01 g/mol (N) = 75.07 g/mol

To find the number of moles of glycine in 28.35 grams, we divide the given mass by the molar mass:

28.35 g glycine / (75.07 g/mol glycine) = 0.377 mol glycine

Therefore, there are 0.377 moles of glycine molecules in 28.35 grams of glycine.

3. a. To find the mass of 1.42 x 10^-4 mol of vitamin C, we multiply the molar mass of vitamin C (176.12 g/mol) by the number of moles:

1.42 x 10^-4 mol x 176.12 g/mol = 0.0248 g

Therefore, the mass of the recommended daily dietary allowance of vitamin C for children aged 4-8 years is 0.0248 grams.

b. The molecular formula of vitamin C is C6H8O6, so there are 6 moles of carbon for every mole of vitamin C. Therefore, there are:

1.42 x 10^-4 mol x 6 = 8.52 x 10^-4 mol of carbon

in 1.42 x 10^-4 mol of C6H8O6.

4. To rank the following from lowest number of particles to highest, we need to compare the number of particles in each of the given amounts.

2.3 mol H2O: 2.3 mol x 6.022 x 10^23 molecules/mol = 1.39 x 10^24 molecules of H2O

3.5 mol H2: 3.5 mol x 6.022 x 10^23 molecules/mol = 2.11 x 10^24 molecules of H2

0.50 mol C100H202: 0.50 mol x 6.022 x 10^23 molecules/mol = 3.01 x 10^23 molecules of C100H202

Therefore, the ranking from lowest to highest number of particles is:

0.50 mol C100H202 < 2.3 mol H2O < 3.5 mol H2.

The reasoning is based on the Avogadro's number which represents the number of particles in one mole of a substance, which is equal to 6.022 x 10^23. The substance with the smallest number of moles has the smallest number of particles, and the substance with the largest number of moles has the largest number of particles.

How many grams of iron are needed to react with 30.0 g of sulfur?

82.3 g
52.3 g
55.8 g
93.6 g

Answers

the solution is 52.3 g (rounded to two decimal places).

If 95 grammes of iron are used in this reaction, how many grammes of sulphur are involved?

We need to know the mass of the iron and sulphur in order to solve for the amount of sulphur involved. 95 grammes make up the iron's bulk. There are 16 grammes of sulphur in total. Hence, 32 grammes of sulphur are used in this reaction.

The correct answer is:

8Fe + S8 → 8FeS

The molar mass of sulfur is 256 g/mol (8 × 32 g/mol), and the molar mass of iron is 56 g/mol.

First, we need to convert the mass of sulfur to moles:

sulphur mass divided by its molar mass yields moles of sulphur.

moles of sulfur = 30.0 g / 256 g/mol

moles of sulfur = 0.1172 mol

According to the balanced equation, 1 mole of sulfur reacts with 8 moles of iron. Therefore, the moles of iron required can be calculated as:

moles of iron = 8 × moles of sulfur

moles of iron = 8 × 0.1172 mol

moles of iron = 0.9376 mol

Finally, we can calculate the mass of iron required using the moles of iron and the molar mass of iron:

Iron's mass is equal to its molar mass and its moles.

mass of iron = 0.9376 mol × 56 g/mol

mass of iron = 52.46 g

In a titration experiment a 300 mL sample of hydrolodic acid (HI) 2.15 M is completely neutralized by 212 mL of an
aqueous solution of rubidium hydroxide (RbOH). What was the molarity of the initial RbOH?
6.45 M RbOH
(orange)
1.52 M RbOH
(magenta)
3.04 M RbOH
(aqua green)

Answers

The balanced chemical equation for the reaction between HI and RbOH is:

HI + RbOH → RbI + H2O

From the equation, we can see that 1 mole of HI reacts with 1 mole of RbOH to produce 1 mole of RbI and 1 mole of H2O.

To determine the molarity of the initial RbOH, we can use the following formula:

Molarity of RbOH = (moles of RbOH) / (volume of RbOH solution in liters)

First, let's calculate the number of moles of HI in the 300 mL sample:

moles of HI = Molarity x volume in liters

moles of HI = 2.15 mol/L x 0.3 L

moles of HI = 0.645 mol

Since 1 mole of HI reacts with 1 mole of RbOH, the number of moles of RbOH used in the titration is also 0.645 mol.

Now, we can use the volume and concentration of the RbOH solution to calculate its molarity:

Molarity of RbOH = (moles of RbOH) / (volume of RbOH solution in liters)

Molarity of RbOH = 0.645 mol / 0.212 L

Molarity of RbOH = 3.04 M

Therefore, the molarity of the initial RbOH solution was 3.04 M, which corresponds to the aqua green option.

Answer:

The balanced chemical equation for the reaction between hydriodic acid (HI) and rubidium hydroxide (RbOH) is:

HI + RbOH → RbI + H2O

From the balanced equation, we can see that the stoichiometry of the reaction is 1:1, which means that 1 mole of HI reacts with 1 mole of RbOH.

Given that a 300 mL sample of HI with a concentration of 2.15 M is completely neutralized by 212 mL of RbOH, we can use the following equation to determine the molarity of RbOH:

Molarity of HI x Volume of HI = Molarity of RbOH x Volume of RbOH

2.15 M x 0.300 L = Molarity of RbOH x 0.212 L

Molarity of RbOH = (2.15 M x 0.300 L) / 0.212 L = 3.04 M

Therefore, the molarity of the initial RbOH solution was 3.04 M, option (aqua green).

What is the molar mass of Hydrochloric Acid?

Answers

Answer:

Explanation:

Hydrochloric acid (HCl) is a binary acid composed of hydrogen and chlorine. The molar mass of hydrochloric acid can be calculated by adding the atomic weights of hydrogen and chlorine.

The atomic weight of hydrogen is 1.008 g/mol, and the atomic weight of chlorine is 35.45 g/mol. Therefore, the molar mass of hydrochloric acid (HCl) is:

Molar mass of HCl = 1 x atomic weight of hydrogen + 1 x atomic weight of chlorine

bash

= 1 x 1.008 g/mol + 1 x 35.45 g/mol

= 36.46 g/mol

Therefore, the molar mass of hydrochloric acid (HCl) is 36.46 g/mol.

calculate the number of zeptomoles (x 10-21 moles) of air trapped inside the container with the movable piston. use your first set of data (15 nm width) to do so

Answers

there are approximately 0.54 zeptomoles of air trapped inside the container with the movable piston.

To calculate the number of zeptomoles of air trapped inside the container with the movable piston, we first need to calculate the volume of the container.

Assuming the container is a rectangular prism with a length and height equal to the size of the graphene sheet (3 cm) and a width equal to the thickness of the spacer (15 nm), the volume of the container can be calculated as:

V = lwh = (3 cm)(3 cm)(15 nm) = 1.35 x 10^-5 cm^3

Next, we need to calculate the number of moles of air trapped inside the container. We can use the ideal gas law to do this:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

We know that the pressure inside the container is equal to atmospheric pressure, which is approximately 101325 Pa (or 1 atm). The temperature is not given, but we can assume it is room temperature, which is approximately 298 K. The ideal gas constant is 8.314 J/(mol*K).

Therefore, we can rearrange the ideal gas law to solve for n:

n = PV/RT

Substituting in the values we know:

n = (101325 Pa)(1.35 x 10^-5 cm^3)/(8.314 J/(mol*K) * 298 K)

n = 5.41 x 10^-28 mol

Ascorbic acid (C₆H₈O₆) is also known as Vitamin C. What quantity in molecules of C₆H₈O₆ does a Vitamin C drink with 1025 mg C₆H₈O₆ contain? Show Math.

Answers

Vitamin C drink with 1025 mg of ascorbic acid contains 3.50 × 10^21 molecules of C6H8O6.

What is Molecules?

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. It is made up of two or more atoms that are chemically bonded together. The atoms can be of the same element, as in the case of diatomic molecules like O2 and H2, or they can be different elements, as in the case of water (H2O) or carbon dioxide (CO2).

First, let's calculate the molar mass of ascorbic acid (C6H8O6):

Molar mass of C = 12.01 g/mol

Molar mass of H = 1.008 g/mol

Molar mass of O = 16.00 g/mol

Molar mass of C6H8O6 = (6 × 12.01) + (8 × 1.008) + (6 × 16.00) = 176.12 g/mol

Now we can use the molar mass to convert the given mass of ascorbic acid into moles:

Number of moles = Mass / Molar mass

Mass of ascorbic acid = 1025 mg = 1.025 g

Number of moles of ascorbic acid = 1.025 g / 176.12 g/mol = 0.00582 moles

Finally, we can use Avogadro's number to convert from moles to molecules:

Number of molecules = Number of moles × Avogadro's number

Number of molecules of C6H8O6 = 0.00582 moles × 6.022 × 10^23 molecules/mol = 3.50 × 10^21 molecules

How could an astronaut benefit from a gyroscope during their training?

Answers

Gyroscope training is advantageous for astronauts because it improves their coordination, balance, and spatial orientation in a microgravity simulation. Also, it can enhance their capacity for jobs in space and help them become less prone to motion sickness.

What function does a gyroscope serve in space?

Gyroscopes in spacecraft alert the onboard computer when the craft has changed orientation (direction and pointing). The stabilising system for the spaceship receives the data from the computer after that.

What kind of training is required for astronauts to travel to space?

To become a fully qualified astronaut, you may need to complete up to two years of training. The International Space Station and the Space Shuttle must be introduced to candidates.

2 moles of calculate the pressure exerted by Co₂ Gas at 27°C and Volume of 4 litres: (dm³)​

Answers

To calculate the pressure exerted by 2 moles of CO2 gas at 27°C and a volume of 4 liters, we can use the ideal gas law:

PV = nRT

where:
- P is the pressure of the gas in atmospheres (atm)
- V is the volume of the gas in liters (L)
- n is the number of moles of the gas
- R is the universal gas constant, which is 0.0821 L⋅atm/mol⋅K
- T is the temperature of the gas in Kelvin (K)

First, we need to convert the volume from dm³ to L by dividing by 1000:

4 dm³ = 4/1000 L = 0.004 L

Next, we need to convert the temperature from Celsius to Kelvin by adding 273:

27°C + 273 = 300 K

Now we can plug in the values and solve for P:

P = (nRT) / V
P = (2 mol x 0.0821 L⋅atm/mol⋅K x 300 K) / 0.004 L
P = 12,315 atm

Therefore, the pressure exerted by 2 moles of CO2 gas at 27°C and a volume of 4 dm³ is approximately 12,315 atm.

In Experiment 2, what was the pressure of the butane gas in the Erlenmeyer flask after the addition of 40 mL of water? Note: Depending on the actual amount of water dispensed in the lab, there is a range of possible answers. Pick the value that is closest to yours.

Answers

The correct answer is d) It depends on the initial pressure and temperature of the gas, volume of the flask, and partial pressure of water vapor.

The pressure of the butane gas in the Erlenmeyer flask after the addition of 40 mL of water cannot be determined without additional information, such as the initial pressure and temperature of the gas, volume of the flask, and partial pressure of water vapor. These factors would need to be known in order to calculate the final pressure of the gas using the ideal gas law.

Therefore, it is important to have accurate experimental data and perform proper calculations to determine the pressure of the butane gas in the Erlenmeyer flask after the addition of 40 mL of water.
