Before preparing the solutions and setup for the procedure, calculate the theoretical amount of 0.5 M NaOH that would be required to neutralize approximately 2.0 g KHP. KHP is a monoprotic acid, the molar mass of KHP = 204.22 g/mol, and the molar mass of NaOH = 40.00 g/mol. Record the volume of NaOH in mL.
