A sample of iron, which has a specific heat capacity of 0.449 J-g g¹c¹, is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The iron sample starts off at 92.5 °C and the temperature of the water starts off at 21.0 °C. When the temperature of the water stops changing it's 23.1 °C. The pressure remains constant at 1 atm. Calculate the mass of the iron sample. Be sure your answer is rounded to 2 significant digits.

A sample of iron, which has a specific heat capacity of 0.449 J-g *, is put into a calorimeter (see sketch at right) that
contains 200.0 g of water. The iron sample starts off at 92.5 °C and the temperature of the water starts off at 21.0 °C. When the
temperature of the water stops changing it's 23.1 °C. The pressure remains constant at 1 atm.
Calculate the mass of the iron sample. Be sure your answer is rounded to 2 significant digits.
