Consider a substance with a heat of solution (AHsin) of -16.7 kJ/mol. 0.00100 mol of this substance was dissolved in water in a calorimeter to create a solution with a total mass of 8.00 g. If the contents of the calorimeter were initially at 20.0C, what will the final temperature be? Assume that the contents of the calorimeter have a specific heat capacity of 4.18 J/(g-K). Express your answer in C using the correct number of significant figures.
