A sample of carbon,3.0g, was burned to carbon dioxide in a copper calorimeter.The mass of the calorimeter was 1.5kg and the mass of water in the calorimeter was 2kg.The initial temperature was 20°c and the final temperature was 31°c.Calculate the heat liberated for the combustion of 1g of carbon. The specific heat capacity of carbon and water are 0.389 and 4.18

I'm at a loss with this problem. Two interpretations:
a. 3.0 g C completely burned. If so then specific heat C isn't needed (since no C is left over). Calculate heat then divide by 3 to find for 1 g.
b. Only 1.0 g of the 3.0 g sample is burned in which case th4e other 2.0 g absorbs some of the heat so heat is absorbed by the calorimeter, the water, and the other 2.0 g C.
