Calculate the weight percent of ascorbic acid in a tablet of Vitamin C using correct significant figures from the following data: A 90 mg sample of a crushed Vitamin C tablet was dissolved in 40 mL of H2SO4 and 20 mL of water. Two grams of KI and 20. mL of 0.0120 M KIO3 solution was added, and the mixture titrated to a starch endpoint. The titration required 12 mL of 0.0530 M thiosulfate solution. Weight = _____ %
