A 59.6 g sample of iron, which has a specific heat capacity of 0.449 J.g¹°C, is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The temperature of the water starts off at 18.0 °C. When the temperature of the water stops changing it's 19.8 °C. The pressure remains constant at 1 atm. Calculate the initial temperature of the iron sample. Be sure your answer is rounded to the correct number of significant digits.
