Question

How many grams will be needed to make a 1.00 Liter solution of 0.500M sodium chloride?

Answer 1

Mass of NaCl = 29.25 g

Further explanation

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

$\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}$

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
