Suppose you add 113.1 grams of ice to 200.1 grams of water in an insulated cup, where the water is initially at 34.9 oC. How many grams of ice remain after the system reaches thermal equilibrium?

The heat capacity of water is 4.184 J/goC and the enthalpy of melting ice is 334 J/g. If all the ice is melted, just enter 0.00

Let the final equilibrium temperature be T deg C.

Heat absorbed by ice while melting = mass x enthalpy of melting ice

= 113.1 x 334 = 37775.4 J.
