If you made a vitamin C solution in 100.0 mL of 0.500 M H₂SO4 and then took a 10.0 mL aliquot of that solution into an erlenmeyer flask along with 2.00 g of KI and 25.0 mL of KIO3,that solution now contains 1/10th the concentration of the tablet. You then titrated vitamin C solution using the back titration technique with a 0.0998 M S₂O32- solution and found that 21.5 mL of solution were needed to reach a colorless endpoint. How many milligrams of vitamin C did you find that the tablet contained experimentally? (do not include the mg unit in your answer, just the number)
