1) Calculate the masses of Ca(NO3)2 x4H2O(s) and KIO3(s) required tomake 10 g of Ca(IO3)2(s). Calculate the amount of Ca(NO3)2 x4H2O(s) needed so that the Ca2+ isin excess of the iodate ion concentration by 20% (i.e., calculate aweight of calcium nitrate that is 20% higher than the minumum required to produce 10 g of calcium iodate).
2) Calculate the mass of Ca(NO3)2 x4H2O(s) required to generate a 0.1XX MCa2+ solution in a 100 mL volumetric flask. (It iswritten as 0.1XX M because you don't know the actual concentration of calcium needed until you weigh the solid and generate the solution, but here is what you need to know:
a) It should beclose to 0.1 M;
b) the final concentration should be known out to 3 significant figures; and
c) you should use the actually generatedconcentration for all of your subsequent calculations
