Students performed a procedure similar to part ii of this experiment (analyzing juices for vitamin c content) as described in the procedure section. three 10.00ml samples of juice were titrated with dcp that had a standardized concentration of 9.98x10-4m. the three titrations took an average of 16.34ml of dcp. calculate the mass (in mg) in 50.00ml of juice. (mm ascorbic acid = 176.124 g/mol)
