A 52.0g sample of iron is put into a calorimeter (see sketch at right) that contains 100.0g of water. The iron sample starts off at 93.9°C and the temperature of the water starts off at 18.0°C. When the temperature of the water stops changing it's 22.9°C. The pressure remains constant at 1atm. Calculate the specific heat capacity of iron according to this experiment. Be sure your answer is rounded to the correct number of significant digits.
