O THERMOCHEMISTRY Solving a basic calorimetry problem O Jacqueline thermometer A 59.2 g sample of iron is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The iron sample starts off at 95.8 °C and the temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 27.1 °C. insulated container The pressure remains constant at 1 atm. water Calculate the specific heat capacity of iron according to this experiment.
