Heat of fusion of ice = 333 Jg^-1

Specific heat of water = 4.184 JK^-1g^-1

a.) Final temperature = ________ degrees C

b.) Calculate the entropy change that occurs during this process.

Entropy change = ________ JK^-1

Please show and explain because I tried doing it but I messed up some distributions and I can't get the right answer.

- Chemistry. Please help!! -
**DrBob222**, Friday, March 2, 2012 at 4:51pmheat absorbed by ice + heat absorbed by water from melted ice at zero C + heat lost by warm water = 0

[mass ice x heat fusion] + [mass melted ice x specific heat water x (Tfinal-Tinitial)] + [mass warm water x specific heat water x (Tfinal-Tinitial)] = 0

Solve for Tfinal, the only unknown in the equation.
