[SOLVED] What is the enthalpy of combustion of magnesium?

Homework Statement

Determine the enthalpy of combustion of Magnesium.

Mg + 1/2O2 --> MgO

magnesium + half oxygen -> magnesium oxide.

The Attempt at a Solution

I am not sure how to calculate this since I don't know where to start. Is there a specific value for this? Or, is there a way we could get these values from a chart or somewhere?

I need help. Thanks.

Review the definition of heat of formation and then reexamine your combustion equation.

Is there a specific value for this?

They should be at the back of your book or try the Index if all fails.

Thanks very much guys for your responses. I found it on the net and basically I had to look for enthalpy of formation of MgO to get my answer. It's -601 kJ.
