Answer to Question #154697 in General Chemistry for Phyroe

Question

Calculate the molar concentration of the acid in 24.3 ml HNO3 are neutralized by 37.2 ml of 1.25 M KOH.

Answer 1

Molar concentration

m₁v₁ = m₂v₂

m₁ = ? , v₁ = 24.3ml , m₂ = 1.25M , v₂ = 37.2ml

m₁ × 24.3ml = 1.25M × 37.2ml

m₁ = $\frac{1.25M×37.2ml}{24.3ml}$

m₁ = 1.9135M

Molar concentration of the acid is 1.9135M
