Potassium perchlorate has a lattice energy of -599 kj/mol and a heat of hydration of -548 kj/mol.

Find the heat of solution for potassium perchlorate when 10.6 g of potassium perchlorate is dissolved with enough water to make 102.7 ml of solution. (J-absorbed)

find the temperature change that occurs when 10.6 g of potassium perchlorate is dissolved with enough water to make 102.7 ml of solution. (Assume a heat capacity of 4.05 J/g*C for the solution and a density of 1.05 g/ml.)
