650. Dilute HCl and 10.00 ml of 0.05000 M KIO3 were added to 25.00 ml of KI solution. The released I2 was distilled off, and excess KI was added to the cooled solution, which reacted with the remaining KIO3. To titrate the released I2, 21.14 ml of 0.1008 N Na2S2O3 was used. Calculate the molar concentration of the initial KI solution.
