27.0 g piece of aluminum (which has a molar heat capacity of 24.03 J/oC mol) is heated to 94.2 oC and dropped into a coffee cup calorimeter containing water initially at 19.9 oC. The final temperature of the water and aluminum mixture is 23.3 oC. Calculate the mass of water in the calorimeter. The specific heat of water is 4.184 J/g oC.
