Suppose that an insulating container of negligible mass contains 0.1 kg of water at a temperature of 19 degrees C. Now suppose 87 g of ice initially at a temperature of -38 degrees C is added to the water. Assuming no transfer of heat to or from the surroundings, what is the final mass (in grams) of the ice (if any) that remains in the system?
