Chemistry Molarity Problem

Question

What is the molarity of a hydrochloric acid (HCl) solution if 20.0 mL of 0.0952 M sodium hydroxide (NaOH) is needed to neutralize 10.5 mL of the acid solution?

Answer 1

M₁ = 0.0952M NaOH

V₁ = 20 mL NaOH

M₂ = ?

V₂ = 10.5 mL HCl

M₁V₁ = M₂V₂

0.0952×20 = M₂×10.5

M₂ = 0. 181M HCl
