The dissolution of cesium hydroxide in water is exothermic (change Hsoln = -71.5

Question

The dissolution of cesium hydroxide in water is exothermic (change Hsoln = -71.55 kJ/mol). Calculate the change in

temperature of a solution produced by dissolving 0.150 kg CsOH (150 g/mol) in 1.00 kg water. Assume the

heat capacity of the solution is 4.18 J/(g*
