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 18.60 g of Cs2SO4(s) are dissolved in 114.40 g of water, the temperature of the solution drops from 22.47 to 20.19 °C. Nested Styrofoam cups Based on the student's observation, calculate the enthalpy of dissolution of Cs2SO4(s) in kJ/mol. Reaccion occurs in solution. Assume the specific heat of the solution is equal to the specific heat of water. AH dissolution kJ/mol
