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