A tablet of vitamin C was analyzed to determine whether it did
in fact contain, as the manufacturer claimed, 1 g of the vitamin.
One tablet was dissolved in water to form 100 mL of solution, and
10 mL of that solution was titrated with iodine (as potassium
triiodide). It required 17.8 mL of 0.0582 M I− 3 (aq) to reach the
stoichiometric point in the titration. If 1 mol I− 3 reacts with 1
mol vitamin C in the reaction, how much vitamin C was in the
tablet? The molar mass of vitamin C is 176 g/mol. Answer in units
of g.
