A 22.2-g piece of Al (which has a molar heat capacity of 24.03 J/mol°C) is heated to 84.6°C and dropped into a calorimeter containing water (the specific heat capacity of water is 4.18 J/g°C) initially at 23.5°C. The final temperature of the water is 27.8°C. Calculate the mass of water in the calorimeter. The correct answer should be 6.2x10g
