Calcium chloride is dissolved in 212 g liquid water in a coffee cup calorimeter. The temperature of the calorimeter and water is initially 25.0∘C. Upon dissolution, the final temperature of the solution and calorimeter is 37.6 ∘C. The heat capacity of the calorimeter is 0.850 kJ/C. The specific heat capacity of the solution is 4.18 J/(gC). The enthalpy of dissolution for calcium chloride is - 81.3 kJ/mol. What mass of calcium chloride was dissolved in this experiment? Hint: The mass of the solution includes water and solute. The units are grams. Do not include units in your answer.
