When 100 photons of light pass through a sample and 64 photons are detected after the passage of light, the number of photons transmitted through the sample is 64.

This is based on the methods of calculating the absorbance of light, which is depicted as the higher the amount of light transmission, the lower the amount of light absorbed.

Thus, when 64 photons of light in 100 photons are detected, 64 photons are transmitted, and therefore, the number of photons absorbed is 36.

Hence, hypothetically, if 100 photons of light are transmitted, 0 photons of light will be absorbed.

Therefore, in this case, it is concluded that the correct answer is 64 photos.

Taking into account the definition of density and scientific notation, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.  That is, density is the relationship between the weight (mass) of a substance and the volume it occupies.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

In this case, you know that:

Replacing in the definition of density:

[tex]density=\frac{0.216 kg}{237 mL}[/tex]

Solving:

density= 0.000911 [tex]\frac{kg}{mL}[/tex]

On the other side, scientific notation is a quick way to represent a number using powers of base 10.  

The numbers are written as a product:

a×10ⁿ

where:

In this case, the density expressed in scientific notation is: 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

In summary, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Average kinetic energy of gases, which is derived from the RMS (root mean square speed) and KE equation, can be solved as:

It appears that the average KE of gases is dependent on the temperature which means that all gases will have the same KE as long the temperature is the same

so 2.46 X 10^28 contains (2.46 X 10^28)/(6.02 X 10^23) =

(2.46 X 10 X 10^27)/ (6.02 x(10^23) = (24.6/6.02) X 10^ (27-23)=

4.09 X 10^4 = 40,900

The biggest change in the body caused by regular exercise is to muscle tissue. ... At the cellular level, exercise triggers the release of substances that dilate the blood vessels in the muscle, letting in more oxygen, says Prof Bradford. These are short-term effects, but deeper changes come with regular exercise.

Exercising causes changes in our body because we're working our muscles so there's more going on with us compared to when we're just laying down. We need more oxygen to go to our muscles so we breathe harder and more rapidly. Our heart also beats faster because it needs to pump more blood to the muscles that are being worked.

Taking into account the definition of dilution,  the new concentration of the solution is 0.2567 M.

First of all, you have to know that   dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

0.385 M× 0.600 L= Cf× 0.900 L

Solving:

Cf= (0.385 M× 0.600 L)÷ 0.900 L

Cf= 0.2567 M

In summary, the new concentration of the solution is 0.2567 M.

Explanation:

We want to find the concentration of the resulting solution of mixing 35mL of a given solution and 0.225 L of water.

We will find that the concentration is 13.5%.

First, we need to write both of these in the same units.

We know that:

1000 mL = 1L

Then:

35 mL = 0.035 L

So when we mix the solution and the water we end with a total volume of:

V = 0.035L + 0.225L = 0.260L

The concentration of solution will be equal to the quotient between the volume of solution we used (0.035 L) and the total volume of the mixture (0.260L)

We will get:

Concentration = (0.035L)/(0.260L) = 0.135

Now to write it as a percentage, we only need to multiply this by 100%.

0.135*100% = 13.5%

This means that the mixture has a concentration of the 13.5%.
