Consider the dissolution of CaCl2.
CaCl2(s) Ca2+(aq) + 2 Cl -(aq) ?H = -81.5 kJ
A 14.1 g sample of CaCl2 is dissolved in 125 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·g.
