How do you calculate the molarity of the #HNO_3# solution?
A pure sample of barium hydroxide of mass 5.68 g was dissolved and diluted to the mark in a 250 mL volumetric flask. It was found that 13.01 mL of this solution was needed to reach the stoichiometric point in a titration of 29.7 mL of a nitric acid solution.

The molarity of the nitric acid was 0.116 mol/L.
Explanation:
This is really a two-part question:
- What is the molarity of the barium hydroxide solution?
- What is the molarity of the nitric acid?
1. Molarity of
The formula for molarity is
#color(blue)(|bar(ul(color(white)(a/a) "Molarity" = "moles"/"litres"color(white)(a/a)|)))" "#
2. Molarity of
The equation for the neutralization reaction is
