If 50.5 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 AH 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?

Feedback:
When the heat of solution is positive, heat is
absorbed in the solution process. Therefore the
temperature of the solution will decrease, not
increase.
