A 54.2 g sample of polystyrene, which has a specific heat capacity of 1.880 J-gc, is put into a calorimeter (see sketch at
right) that contains 100.0 g of water. The temperature of the water starts off at 21.0 °C. When the temperature of the water stops
changing it's 34.3 °C. The pressure remains constant at 1 atm.
Calculate the initial temperature of the polystyrene sample. Be sure your answer is rounded to the correct number of significant
digits.
