I AM SO CONFUSED PLEASE HELP:( When ice at 0°C melts to liquid water at 0°C, it absorbs 0.334 kJ of hear per gram. Suppose the heat needed to melt 49.5 g of ice is absorbed from the water contained in a glass. If this water has a mass of 0.219 kg and a temperature of 21.0°C, what is the final temperature of the water? Assume the specific heat is that of pure water, 4.18 J/(g-°C). (Note that you will also have 49.5 g of water at 0°C from the ice.)
