# Assume the specific heat of the solution is equal to the specific heat of water. ΔHdissolution = kJ/mol????

## 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 5.07 g of CsClO4(s) are dissolved in 102.30 g of water, the temperature of the solution drops from 23.03 to 19.93 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.80 J/°C. Based on the student's observation, calculate the enthalpy of dissolution of CsClO4(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. ΔHdissolution = kJ/mol
