Calculate the entropy change that occurs when a 13.5 gram piece of ice at 0deg C is placed into a styrofoam cup containing 124.0 grams of water at a temperature of 78.0deg C. Assume that there is no loss or gain of heat to or from the surroundings. Enter your answer in J/K as a number in scientific notation without units. The heat of fusion of water is 333 J/g. Assume that the specific heat of H2O(l) is constant at 4.184 JK-1g-1.
