The overall reaction (oxidation of ascorbic acid by potassium iodate) can be 
represented by the following equation: 
3 HC6H7O6(aq) + KIO3(aq)            3 C6H6O6(aq) +  KI(aq)  +  3 H2O
Given, 
Mass of KIO3 = 0.8000 g 
Moles of KIO3 = 0.8000/214.00 = 0.0037          (Mol.Wt. of KIO3 = 214.00 g/mol) 
This amount is dissolved in 250 ml solution.  
So, 1000 ml of this solution contains 0.0037 x (1000/250) = 0.0148 moles.  
Hence, the concentration of the KIO3 solution = 0.01480 M (moles/Liter)     
(Molarity = Number of moles dissolved in 1 Liter i.e. 1000 ml solution) 
Given:  13.
