In the laboratory a general chemistry student finds that when 2.84 g of CuCl2(s) are dissolved in 102.00 g of water, the temperature of the solution increases from 24.81 to 27.26 °C.
The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.64 J/°C.
Based on the student's observation, calculate the enthalpy of dissolution of CuCl2(s) in kJ/mol.
Assume the specific heat of the solution is equal to the specific heat of water.
