Thermochemistry and calorimetry

If 80.5 g of KBr are dissolved in 400.0 g of water at 25.0 °C in an insulated container, a temperature change is observed. The ∆H of solution of KBr is 19.9 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?
