When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 2.93 g of CaBr2(s) are dissolved in 110.60g of water, the temperature of the solution increasesfrom 24.61 to 27.93 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.90 J/°C.Based on the student's observation, calculate the enthalpy of dissolution of CaBr2(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water.ΔHdissolution = kJ/mol

A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.502-g sample of para-toluic acid (C3H3O2) in a bomb calorimeter containing 1170. g of water. The temperature increases from 25.10 °C to 27.60 °C.
