Question

Calculate the mass in grams of NaCl required to prepare 0.500 L of a 0.500 M solution.

Answer 1

14.61 g NaCl

Step-by-step explanation:

Molarity = moles / volume of solution (litres)

0.500 = moles / 0.500 L

moles = 0.25

Molar mass of NaCl is 58.44 g NaCl /1 mol NaCl.

0.25 moles NaCl x 58.44 g NaCl /1 mol NaCl

= 14.61 g NaCl
