Potassium perchlorate (KClO4) has a lattice energy of 599 kJ/mol and a heat of hydration of 548kJ/mol. Find the heat of solution for potassium perchlorate when 10.9g of potassium perchlorate is dissolved with enough water to make 1159mL of sclution Express your answer using two significant figures. Delermine the tenperature change that occus when 109g of potassi im perchlorate is dissolved wich enough waler fo make 1159 mi, of solution. (Assume a heat capacty of 405J/g:. C for the solution and a density of 1.05g/mL ) Express your answer using two significant figures
