Potassium perchlorate (KClO4) has a lattice energy of -599 kJ/mol and a heat of hydration of -548 kJ/mol.

1. Find the heat of solution for potassium perchlorate when 10.5 g of potassium perchlorate is dissolved with enough water to make 100.7 mL of solution.Express your answer using two significant figures.

q=______J absorbed

2. Determine the temperature change that occurs when 10.5 g of potassium perchlorate is dissolved with enough water to make 112.0 mL of solution. (Assume a heat capacity of 4.05 J/g??C for the solution and a density of 1.05 g/mL.) Express your answer using two significant figures.

Delta t=_________?C
