A 15.0 g sample of CaCl2(110.98 g/mol) is dissolved in 175 g of water initially at 23.5 degrees C. The final temperature of this solution is 37.6 degrees C. Assuming no heat loss to the surroundings, calculate the amount of heat released in this experiment.

CaCl2 (s) --> Ca^2+ (aq) + 2Cl^- (aq)

A generic solid, X, has a molar mass of 75.3 g/mol. In a constant-pressure calorimeter, 16.9g of X is dissolved in 267g of water at 23.00 degrees Celsius. X(s) --> X(aq) The temperature of the resulting solution rises to 24.50 degrees Celsius. Assume the solution has the same specific heat as water, 4.184J/(g.C) and that's negligible heat loss to the surroundings. How much heat was absorbed by the solution? What is the enthalpy of the reaction? Thanks!

A 3.98 g sample of solid NaBr (s) is dissolved in 361 mL of water in a coffee cup calorimeter. Once all of the NaBr (s) is dissolved in the water, the final temperature of the solution is found to be 30.04°C. If the initial temperature of the water in the calorimeter was 21.84 °C, calculate the calorimeter constant (in J/K) for the coffee cup calorimeter. The heat of solvation of NaBr (s) is -0.60 kJ/mol.
