A student is conducting molecular weight determination of an unknown diprotic acid. He first prepared a 250 mL of 0.15 M NaOH (39.997 g/mol) titrant solution, which he then standardized with 0.7625 g of KHP (204.22 g/mol) which consumed 26.32 mL of the titrant. After standardization, he weighed 0.0996 g of unknown diprotic acid and the titration reached the endpoint at a volume of 11.68 mL. What is the molar mass of the diprotic acid? O 90 g/mol O 60 g/mol 120 g/mol 100 g/mol 180 g/mol
