5.00 mL sample of 0.1136 M of standard ascorbic solution required to 12.70 mL of KlO3 to reach the endpoint. The same KlO3 solution was then used to titrate 10.00 mL sample of a peach solution and it required 8.50 mL to reach the endpoint. Determine the: A.) Mass in Mg of I2 formed prior to the endpoint, and B.) Molarity of KlO3.
