A sample of polystyrene, which has a specific heat capacity of 1.880 J'g .°C', is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The polystyrene sample starts off at 95.2 °C and the temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 32.4 °C. The pressure remains constant at 1 atm. Calculate the mass of the polystyrene sample. Be sure your answer is rounded to 2 significant digits.
