Thermometer 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. Cardboard or Styrofoam lid In the laboratory a general chemistry student finds that when 2.02 g of CaCl,(s) are dissolved in 114.00 g of water, the temperature of the solution increases from 23.70 to 26.89 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.74 J/°C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of CaCl2(s) in kJ/mol.
