The specific heat capacity of an unknown metal is to be found using calorimetry. A 35.0g sample of the metal is placed into a boiling water bath at a temperature of 100.0ºC. In the calorimeter lies 101.1g of water at a temperature of 22.1ºC. After thorough heating of the metal, it is transferred to the calorimeter. The final temperature of the metal/water system is 22.9ºC. Calculate the specific heat capacity of the metal.
