A tablet of vitamin C was analyzed to determine whether it did in fact contain, as the manufacturer claimed, 1 g of the vita-min. One tablet was dissolved in water toform 100 mL of solution, and 10 mL of thatsolution was titrated with iodine (as potas-sium triiodide). It required 21.5 mL of 0.0551 M I^(-3) (aq) to reach the stoichiometric point inthe titration. If 1 mol I-3 reacts with 1 mol vi-tamin C in the reaction, how much vitamin C was in the tablet? The molar mass of vitaminC is 176 g/mol.
