A scientist conducted the volumetric analysis using both Parts A and B and obtained the following data: 0.4985g KHP (molar mass of 204.23 g/mol ) was titrated to endpoint with 15.05mL of NaOH as in Part A. Then as in Part B, 25.0mL of unknown concentration of HCl was titrated to the endpoint with 21.50mL of NaOH. What is the concentration of HCl? Mass of KHP: __________ Moles of KHP: __________ Moles of NaOH at equivalence point: __________ Volume of NaOH used to neutralize KHP: __________ Molarity of NaOH in the buret: __________ Volume of NaOH used to neutralize HCl: __________ Moles of NaOH used to neutralize HCl: __________ Moles of HCl: __________ Volume of HCl used for titration: __________ Molarity of HCl: _____
