Ice at 0°C is placed in a Styrofoam cup containing 0.32 kg of lemonade at 27 °C. After the ice and water reach equilibrium, some ice still remains. Latent heat of fusion for water = 3.35x105 J/kg. Specific heat capacity lemonade = 4180 J/kg °C. Assume that the cup absorbs no heat during this process since its mass is extremely small. Calculate the mass of ice that melted.
