# Problem: Potassium perchlorate (KClO4) has a lattice energy of -599 kJ/mol and a heat of hydration of -548 kJ/mol.Determine the temperature change that occurs when 10.6 g of potassium perchlorate is dissolved with enough water to make 110.1 mL of solution. (Assume a heat capacity of 4.05 J/goC for the solution and a density of 1.05 g/mL.)

We have to calculate the change in temperature that occurs when 10.6 g potassium perchlorate is dissolved to make 110.1 mL of solution.

Heat of solution is the energy absorbed or released when a solid is dissolved in a solvent to form a solution.

The heat of solution is calculated by this formula: ###### Problem Details
