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 1.90 g of CoCl2(s) are dissolved in 115.20 g of water, the temperature of the solution increases from 25.04 to 27.51 °C.

The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.85 J/°C.

Based on the student's observation, calculate the enthalpy of dissolution of CoCl2(s) in kJ/mol.

Assume the specific heat of the solution is equal to the specific heat of water.
