SAMPLE EXERCISE 16-32 on PAGE 392 A 0.9471 g sample of dimethylphthalate, C.H(COOCH3)2 (M.M. = 194.19 g/mole), and unreactive species was refluxed with 50.00 mL of 0.1215 M NaOH to hydrolyze the ester groups. C.Ha(COOCH3)2 + 20H + C H (COO)22 + 2CH3OH After the reaction was complete, the excess NaOH was back-titrated with 24.27 mL of 0.1644 M HCI. Calculate the percentage of dimethylphthalate (dmp) in the sample. Question 3 3 p 3. Based on the balanced chemical equations, the analyte Ais the reagent Ris and the back-titrant is Write the chemical name of the analyte A in lowercase letters. For the reagent R. write the chemical formula For the back-titrant T. write the chemical formula
