How to calculate heat of combustion?

[312213]

Homework Statement

Calculate the heat of combustion per mole of glucose(s), C6H12O6(s).

This is the only information given. There is no Hess' law equations or any of the sort.

The Attempt at a Solution

I already know the answer is roughly -2813kJ/mole but I don't understand how to arrive to the answer with this little information. I would like to be given some sort of direction that could help me calculate to -2813kJ/mole.

Write the balanced equation for C6H12O6 + xO2 -> whatever
Find how many bonds are broken/made
Look up the bond energy
A bit of arithmatic

For what's it's worth, I agree with the above poster. Draw a Lewis Dot structure and figure out the bonds. Bond energy=delta H of reaction = Bonds broken (reactants) - Bonds formed (final products). You can look up these values online or in your textbook. =)
