A sample of aluminum, which has a specific heat capacity of 0.897·J·g−1°C−1, is put into a calorimeter (see sketch at right) that contains 250.0g of water. The aluminum sample starts off at 85.1°C and the temperature of the water starts off at 23.0°C. When the temperature of the water stops changing it's 25.8°C. The pressure remains constant at 1atm. Calculate the mass of the aluminum sample. Be sure your answer is rounded to 2 significant digits.
