A 20.0-g sample of ice at -10.0 oC is mixed with 100.0g of water at 80.0 oC. Calculate the final temperature of the mixiture assuming no heat loss to the surroundings. The heat capacities of H2O(s) and H2O(l) are 2.08 and 4.18J/goC respectively, and the enthalpy of fusion for ice is 6.02kJ/mol.
I understand that I have to make the energy gained by the ice equal to the energy lost by the liquid water, but I don't know what to put on each side due to the phase changes. Where do I use enthalpy of fusion?
