The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. Thermometer Cardboard or In the laboratory a general chemistry student finds that when 0.76 g of MgCl2(s) - Styrofoam lid are dissolved in 105.70 g of water, the temperature of the solution increases from 24.28 to 27.28 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.61 J/°C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of MgCl2(s) in kJ/mol. - Reaction occurs in Assume the specific heat of the solution is equal to the specific heat of water. solution.
