What is the molarity of a salt solution made by dissolving 280.Omg of NaCl in 2.00mL of water. Assume the final volume is the same as the volume of the water.
Answer:
The molarity of a solution tells you how many moles of solute you get per liter of solution.Notice that the problem provides you with the volume of the solution expressed in milliliters mL.Right from the start you should remember that you must convert this volume to liters by using the conversion factor1 L=10+3mL

1) Find the mass of 2.7 moles of NaCl.
Answer:
157. 788 grams
Explanation:
number of moles = mass/molar mass.
hence the mass = molar mass × number of moles
m = 58.44 × 2.7 = 157.788 grams
The term mole concept is used here to determine the mass of sodium chloride. The mass of 2.7 moles of NaCl is 157.78 g.
What is a mole?One mole of a substance is defined as that quantity of it which contains as many entities as there are atoms exactly in 12 g of carbon - 12. The formula used to calculate the number of moles is:
Number of moles = Given mass / Molar mass
The mole concept is a convenient method to express the amount of a substance. The elementary particles in moles may be atoms, ions, molecules etc.
The molar mass of NaCl = 58.44 g/mol
Here the number of moles of NaCl = 2.7
Mass = Molar mass × Number of moles
58.44 g/mol × 2.7 = 157.78 g
Thus the mass of NaCl is 157.78 g.
