When a solid dissolves in water, the solution may become hotter or colder. The dissolution enthalpy (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 14.44 g Cs,SO4(s) is dissolved in 119.20 g water, the temperature of the solution drops from 24.80 to 23.20 °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 dissolution enthalpy of CS2SO4(s) in kJ/mol. Assume the specific heat capacity of the solution is equal to the specific heat capacity of water.
