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 2.62 g of CuCh(s) are dissolved in 115.60 g of water, the temperature of the solution increases from 23.23 to 25.26 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.73 J/°C. Nested Based on the student's observation, calculate the enthalpy of dissolution of CuCl(s) in kJ/mol. Styrofoam cups Assume the specific heat of the solution is equal to the specific heat of water. Reaction occurs in AHdissolution =| kJ/mol solution.
