A student is conducting molecular weight determination of an unknown diprotic acid. He fiırst prepared a 250 mL NaOH (39.997 g/mol) titrant solution, which he then standardized with 0.5830g of KHP (204.22 g/mol) which consumed 24.02 mL of the titrant. After standardization, he weighed 0.2108 g of unknown diprotic acid and the titration reached the endpoint at a volume of 21.58 mL. What is the standardized concentration of the titrant? ( Select) What is the molar mass of the diprotic acid? [Select ]
