The molar heat of solution of a substance is found to be +21.38 kJ/mol. The addition of 0.100 mol of this substance to 1.000 L of water initially at 40.0 °C results in a temperature decrease. Assume the specific heat of the resulting solution to be equal to that of pure water. Find the final temperature of the solution (Also assume that the heat capacity of th calorimeter is negligible.)

A 50.0 g sample of water at 70.0 °C is mixed with 60.0 g of water at 20.0 °C. Find the final temperature of the mixture if no heat is transferred to or from the container or surroundings.

Suppose the calorimeter cup was not completely dry when you added 50.0 mL of 1.00 M HCI. How would this oversight change the calculated value of AHneut?
