Consider the dissolution of CaCl2:
CaCl2 (s) → Ca2+(aq) + 2 Cl- (aq) ΔH = -81.5 kJ
An 11.0-g sample of CaCl2 is dissolved in 125 g water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat loss to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C•g.
