Mass of NaCl = 29.25 g
<h3>Further explanation</h3>
Given
A 1.00 Liter solution of 0.500 M Sodium chloride
Required
Mass of NaCl
Solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

Input the value :
n = M x V
n = 0.5 x 1
n = 0.5 mol
Mass NaCl :
= mol x MW
= 0.5 x 58.5
= 29.25 g
