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 8.18g of NaClO4 (s) are dissolved in 118.60g of water, the temperature of the solution drops from 23.97 to 21.89C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.62J/C. Based on the student's observation, calculate the enthalpy of dissolution of NaClO4(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. Hdissolution=kJ/mol
