A 1.037g vitamin C tablet is crushed, treated, and diluted to 100.00mL in a volumetric flask with deionized water. Three 5.00mL samples of this solution are titrated with DCP that had a standardized concentration of 9.94x10-4M. The three titrations took an average of 27.51mL of DCP. (MM Ascorbic Acid = 176.124 g/mol)
Calculate the mass (in mg) in the vitamin C tablet. (MM Ascorbic Acid = 176.124 g/mol)
