A sample of brass, which has a specific heat capacity of 0.375 Jgc, is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The brass sample starts off at 96.0 °C and the temperature of the water starts off at 21.0 °C. When the temperature of the water stops changing it's 22.9 °C. The pressure remains constant at 1 atm. Calculate the mass of the brass sample. Be sure your answer is rounded to 2 significant digits.
