Question

9. Find the molarity (M) of a solution which
contains 0.50 mol NaOH in 875 mL of solution.

Answer 1

Molarity (M) = number of moles of solute (n) / volume of solution in liters (V)

Given,

number of moles of solute (n) = 0.50 mol

volume of solution = 875 mL = 875/1000 L = 0.875 L

Molarity (M) = 0.50 mol / 0.875 L = 0.57 M
