An aqueous potassium iodate stock solution is made by dissolving 7.18 mol KIO, in sufficient water for the final volume of the solution to be 3.40 L. Calculate the molarity of the stock KIO3 solution. molarity of stock KIO2 solution= M A 10.0 mL aliquot is removed from the described stock solution and diluted to a total volume of 100.0 mL. Calculate the molarity of the dilute solution. molarity of dilute KIO3 solution= M
