If 40.5 g of KCl are dissolved 250.0 g of water at 25.0 C in an insulated container, a temperature change is observed. The H of solution of KCl is 17.2 kJ/mol. Assuming that the specific heat of the solution is 4.184 J/(g C), and that no heat is gained or lost by the container, what will be the final temperature of the solution?
