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 41 g of CaCl s are dissolved in 114 80 g of water the temperatur of the solution increases from 24 47 to 26 70 C The heat capacity of the calorimeter sometimes referred to as the calorimeter constant was determined in a separate experiment to be 1 59 J C Based on the student s observation calculate the enthalpy of dissolution of CaCl s in kJ mol Assume the specific heat of the solution is equal to the specific heat of water AH dissolution kJ mol
