When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolutlon (dissolving) can be determined using a coffee cup calorimeter. Thermometer Cardboard or In the laboratory a general chemistry student finds that when 3.98 g of CsCIO,) are dissolved in 113.50 g of water, the temperature of the solution drops from 22.76 to 20.63 C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.55 1C. Styrofoam tid Nested Styrofoam cups Based on the students observation, calculate the enthalpy of dissolution of CSCIO,s) in kJmol. Assume the specific heat of the solution is equal to the specific heat of water. Reaction occurs in solution. AHissolution k/mol
