students performed a procedure similar to part iii of this experiment. a vitamin c tablet is crushed, treated, and diluted to 100.00 ml in a volumetric flask with deionized water. three 5.00 ml samples of this solution are titrated with dcp that had a standardized concentration of 0.00112 m. the three titrations took an average of 18.89 ml of dcp. calculate the mass of aa (in mg) in the vitamin c tablet.
