  I firstly figured the ratio between the 5kg of CuSo4 to water and then find moles of Cus04 5h2o but ended up with 1.345kg but the answer is 1.523kg

 

 

5 kg of anhydrous CuSO4 are mixed with 20 kg of water. The mixture is then kept at 20°C
until the maximum possible amount of CuSO4 has dissolved. Any undissolved CuSO4 is
hydrated to form solid CuSO4∙5H2O. Calculate the mass of undissolved solid.
Data:
Molecular Masses: CuSO4 = 159.6; CuSO4∙5H2O = 249.7
Solubility at 20°C: 20.7 kg CuSO4 per 100 kg water.

You should reduce the problem to two equations. Then solve them algebraically.

Maybe "the answer" is wrong.
