Hi, i'm trying to do a chemistry problem and i've tried a couple answers and they have been wrong..so if anybody knows how to do this.. that would be fantastic 
thanks-
In the following experiment, a coffee-cup calorimeter containing 100 of is used. The initial temperature of the calorimeter is 23 . If 7.70 of CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution (change in) Hsol of CaCl2 is -82.8 kj/mol.
the answer should be in deg celcius.
