Homework Help: Physics

Posted by Melissa on Tuesday, December 7, 2010 at 12:39am.

A 3.9010^2kg cube of ice at an initial temperature of -18.0degreesC is placed in 0.480kg of water at 41.0degreesC in an insulated container of negligible mass.

Calculate the change in entropy of the system.

I found the equilibrium temperature to be at 304.9K, then used
change in S = mass*c*ln(T2/T1) where T2 is the final temperature and T1 is the initial temperature.
But my answer was wrong.
