When ice at 0°C melts to liquid water at 0°C, it absorbs 0.334 kJ of heat per gram. Suppose the heat needed to melt 30.7 g of ice is absorbed from the water contained in a glass. If this water has a mass of 0.189 kg and a temperature of 21.0°C, what is the final temperature of the water? (Note that you will also have 30.7 g of water at 0°C from the ice.)
