Homework Help: Chemistry

Posted by Kalli on Tuesday, September 25, 2012 at 11:39pm.

When 0.312g of glucose was burned in a bomb calorimeter (heat capacity 641 J/K) the temperature rose by 7.739 K. Calculate the standard enthalpy of combustion and the standard internal energy of combustion.

I've calculated the standard enthalpy but am unsure of how to go about finding the standard internal energy. Any suggestions?
