2. If 1.0120 g of potassium iodate were used to make the 500.0 mL solution, what is the molarity of potassium iodate? 3. If 39.98 mL of thiosulfate solution were needed to completely titrate 50.00 mL of potassium iodate from the above solution, what is the concentration of the thiosulfate? 4. How many moles of I3¬ can be generated from 50.00 mL of KIO3 (from question #2)? 5. If 16.11 ml of standardized thiosulfate (from question #3) is reacted with 50.00 mL of KIO3 and a portion of a vitamin C tablet, how many moles of I3 react with the thiosulfate? (Hint: Don't forget the mole ratios.) How many moles of I3¯ are left to react with the vitamin C? moles react with S2032- moles react with Vit. C
