A 52.4 g sample of brass is put into a calorimeter (see sketch at right) that contains 150.0 g of water. The brass sample starts off at 95.1 °C and the temperature of the water starts off at 15.0 °C. When the temperature of the water stops changing it's 17.6°C. The pressure remains constant at 1 atm. container water Calculate the specific heat capacity of brass according to this experiment. Be sure your answer is rounded to 2 significant digits. sample a calorimeter x 10 oC.
