8. Calculate the mass of KHP (molar mass 204.44 g/mol) that reacts with 15 mL of the NaOH solution in the procedure. Express mass of KHP with the correct number of significant figures. Record answer in lab assignment. Ono ON 19 9. a. A 0.411 g sample of KHP is dissolved with 50.00 mL of deionized H;O in a 125-mL Erlenmeyer flask. The sample is titrated to the endpoint with 15.17 mL of a NaOH solution. What is the molar concentration of the NaOH solution? Give answer to the correct number of significant figures. b. A 25.00 mL aliquot of nitric acid (HNO3) of unknown concentration is pipetted into a 125- namL Erlenmeyer flask and 2 drops of phenolphthalein are added. The above NaOH (titrant) solution is used to titrate the HNO3 (analyte). If 16.77 mL of titrant is used to reach the endpoint, what is the molar concentration of the nitric acid? Give answer to the correct number of significant figures. Sobne
