A 25.0 g piece of Aluminum (which has a molar heat capacity of 24.03J/Cmol) is heated to 82.4C and dropped into a calorimeter containing water (specific heat capacity of water is 4.18 J/gC) initially at 22.3C. The final temperature of the water is 24.9C. Calculate the mass of water in the calorimeter.
