Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations.
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 250.0 g of water. The polystyrene sample starts off at 85.5 °C and the temperature of the water starts off at
24.0 °C. When the temperature of the water stops changing it's 29.7 °C. The pressure remains constant at 1 atm..
Calculate the mass of the polystyrene sample. Be sure your answer is rounded to the correct number of significant digits.
25.7 g
