An aqueous potassium iodate (KIO3) solution is made by dissolving 553 grams of KIO3 in sufficient water so that the final volume of the solution is 2.10 L. 

1.) Calculate the molarity of the KIO3 solution.

2.) Calculate the molarity of the two solutions.

a) 0.650 mol of NaOH in 1.45 L of solution.

b) 10.9 g of NaCl in 699 mL of solution.

3.) If 2.86 g of CuNO3 is dissolved in water to make a 0.450 M solution, what is the volume of the solution?
