CaCl2(s) Ca2+(aq) + 2 Cl-(aq)
H = -81.5 kJ
A 14.0 g sample of CaCl2 is dissolved in 130. g of water, with both substances at 25.0C. 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/Cg.
I need a step by step process on how to do this.
