Seeking a more comfortable homework help environment? Homework Clinic
1d. determine the number of grams of water required at 100 Celsius to dissolve a mixture containing 20 g KNO3 and 2.0 g CuSO4*5H20 assuming that the solubility of one substance is not affected by the presence of another.

2. to the solution in Problem 1d at 100 Celsius, 15g of water are added and the solution is cooled to 0 Celsius

a. How much KNO3 remains in solution (see figure 1 )
b. How much KNO3 crystallizes out?
c. How much CuSO4*5 H2O crystallizes out?
d What percent of the KNO3 in the sample is recovered?

To solve this problem, you need the solubilty data of KNO3 in water from 0 to 100 C. To determine mass which crystallizes out, subtract the solubility of KNO3 at the lower temperature from that at the higher temperature.

I think the following writeup may help you
