A 248-gram piece of aluminum initially at 94.1°C is dropped into water in a coffee-cup calorimeter initially at 2.2°C.  If the final temperature of the aluminum and water is 18.7°C, what mass (in g) of water is present in the calorimeter? Assume all heat transfer occurs between the aluminum and water, and that the density of water over the relevant temperature range is 0.997 g/mL.  Show all work, and highlight your answer in a readable background color.
