In an experiment, when 23.6 of calcium chloride, CaCl2 were dissolved in water in a coffee-cup calorimeter (at constant pressure), the temperature rose from 25.0°C to 38.7°C. The dissolution process is: CaCl2(s) Ca2+ (aq) + 2Cl-(aq) The heat capacity of the solution and the calorimeter is 1258 J/°C. The molar mass of CaCl2 is 110.98 g/mol. What is the heat that was absorbed by the solution and calorimeter? What is the heat that was released from the dissolution of CaCl, in the experiment?
