A vitamin C tablet weighing 1.632 g was dissolved into an acidic KI solution containing a starch indicator. The solution was then titrated to a blue-black endpoint with 26.0mL of a 0.0163 M KIO3 solution. How many mg of Vitamin C were in the tablet ?? and what % of the powder was Vitamin C?? Please solve this out for me
