075 kg ice cube at 0 degree C is dropped into an insulated Styrofoam cup holding 0.33 kg of water at 25.0 degree C.

A 0.075 kg ice cube at 0 degree C is dropped into an insulated Styrofoam cup holding 0.33 kg of water at 25.0 degree C. Calculate the final temperature of the system, neglecting the heat loss to the cup and the Outside. The specific heal of water is 4.2 kJ/kg0 degree C and the latent heat of melting of ice is 335 kJ/kg.
