Exercise of Nuclear reactor physics by ing. Giorgio Bertucelli.

The energy released when carbon (graphite) is burned to carbon dioxide is 32797J/g . What is the energy released for atom of carbon? (Graphite density is 2.25g/cm³).


Solution
From table of atomic raddi we read for C:


The volume of an atom of C:

The mass of C:


Then energy per atom is:
