Question

What mass of NaCI us need to make 1.50L of a 2.00 M (mol/L) Solution

Answer 1

175.32 g

Step-by-step explanation:

Molarity(M) = moles solute/volume of solution

2.00 M = moles NaCl / 1.50 l

moles NaCl = 2.00 M x 1.50 l = 3.0

molar mass NaCl = 22.99 + 35.45 = 58.44 g/mole (from Periodic Table)

mass NaCl = (3.0 moles)(58.44 g/mole) = 175.32 g
