Thermometer Cardboard Styrofoan 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 5.93 g of CSCIO4(s) are dissolved in 108.70 g of water, the temperature of the solution drops from 25.22 to 21.78 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.89 /°C. Based on the student's observation, calculate the enthalpy of dissolution of CCIO (S) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water.
