2. Assay of Vitamin C: add 100 ml of freshly boiled and cooled water and 10 ml of dilute acetic acid to dissolve, add 1 ml of starch IS, titrate immediately with iodine (0.0515 mol/L) Vs until a blue color persists for at least 30 seconds (Titrant consumption: 22.15 mL). Each ml of iodine (0.05 mol/L) VS is equivalent to 8.806 mg of C,H&O6 (T=8.806mg/mL). Please calculate the content of the Vitamin C sample. To an accurately weighed 0.2015 g of the Vitamin C (CaH&Os) being examined,
