Suppose 13.00 mL of 0.100 M barium hydroxide is required to neutralize 17.00 ml of nitric acid with an unknown concentration. What is the concentration of the nitric acid. Express your answer in mol/L

To solve for the concentration of nitric acid in mol/L or also M. We use the equation,

M₁V₁ = M₂V₂

Where M stands for the molarity and V is for volume. Substituting the known values,

(0.10 M) (13.0 mL) = (M₂) (17 mL)

M₂ = 0.076 M

Thus, the concentration of the nitric acid is approximately 0.076 M.
