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 1.85 g of CaCl2(s) are dissolved in 114.50 g of water, the temperature of the solution increases from 23.01 to 25.89 °C The heat capacity of the calorimeter (sometimes referred to as the calortmeter constant) was determined in a separate experiment to be 1.71 J/OC Based on the student’s observation, calculate the enthalpy of dissolution of CaCl2(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. kJ/mol
