Calculate the molarity of a solution prepared by dissolving 11.5 g of solid NaOH in enough water to make 1.50 L of solution. . Step 12 Repeat the titration with fresh samples of KHP until you have two concentrations that agree within 1.5 %. $\text{V}_A$ and $\text{V}_B$ are the volumes of the acid and base, respectively.
