When the CaCl2(s) is added to water, the following reaction occurs. CaCl2(s) → Ca2+(aq) + 2Cl–(aq) ΔH = – 81.5 kJ A 36.6 g sample of CaCl2 is dissolved in water, with both substances at 25.0 °C. Calculate the final temperature (in °C) of the solution assuming no heat is lost to the surroundings, the final solution, containing CaCl2 and water, has a mass of 100.0 g and the solution has a specific heat capacity of 4.18 J °C–1g –1. The molar mass of CaCl2 = 110.98 g/mol
