1 Acid – Base Calculations Calculating KHP and NaOH E.g. 3.75 g of KHP was dissolved in a total of 50.0 mL with an indicator added. It takes 38.3 mL of the NaOH to reach the end point of the KHP solution. What is the molarity of the NaOH solution? What mass of KHP is necessary to react with 50.0 mL of 0.500 M NaOH? Calculating moles in a certain volume of a given molar concentration. c E.g. How many moles of H 2 SO 4 are there in 48.5 mL of 0.275 M H 2 SO 4 solution? c E.g. How many moles of H + ions are there in 48.5 mL of 0.275 M H 2 SO 4 solution? Calculating Solution Stoichiometry c How many moles of NaOH will react with 48.5 mL of 0.275 M H 2 SO 4 solution?
