Use average bond energies together with the standard enthalpy of formation of C(g) (718.4 kJ/mol) to estimate

Question:

Use average bond energies together with the standard enthalpy of formation of C(g) (718.4 kJ/mol) to estimate the standard enthalpy of formation of gaseous benzene, C₆H₆(g). (Remember that average bond energies apply to the gas phase only.)

Compare the value you obtain using average bond energies to the actual standard enthalpy of formation of gaseous benzene, 82.9 kJ/mol. What does the difference between these two values tell you about the stability of benzene?
