If 40.5 g of KCI are dissolved 250.0 g of water at 25.0 °C in an insulated container, a temperature change is observed. The AH of solution of KCI 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?
