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 18.08 g of BaBr2(s) are dissolved in 111.20 g of water, the temperature of the solution increases from 24.15 to 26.91 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.81 J/°C. Based on the student's observation, calculate the enthalpy of dissolution of BaBr2(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water.
