Exactly 3.0 g of carbon was burned to C02 in a copper calorimeter. The mass of the calorimeter is 1500 g, and there is 2000 g of water in the calorimeter. The initial temperature was 20 °C, and the final temperature is 31 °C. Calculate the heat given off per gram of carbon. cCu = 0.093 cal/g·°C. Neglect the small heat capacity of the carbon and carbon dioxide.

Solution:
Exactly 3.0 g of carbon was burned to C02 in a copper calorimeter. The mass of t
