**drwls**, Wednesday, May 27, 2009 at 2:30amThe heat absorbed by the ice in melting and rising to equilibrium temperature equals the heat lost by the rest of the water. Let T be the final temperature.

0.5kg*4.190(90 - T) = 0.5kg*(L + 4.190T)

The 0.5 kg cancels out since the masses are equal. You know what L is; solve for T.

4.190(90-T) = 333 + 4190T

2*4.190T = 377.1 -333 = 44.1

T = 5.3C
