How do you solve this?

Question

Calculate the volume in liters of a 1.2

M sodium chloride solution that contains 150.g

 of sodium chloride NaCl

. Round your answer to 2

 significant digits.

Answer 1

First convert grams of NaCl to moles using the molecular weight: 150 g / 58 (g/mole) = 2.6 moles

Then using the molarity we can convert moles to liters: 2.6 moles / 1.2 (moles/liter) = 2.2 liters
