You need to take the ratio of the mass of nitrogen to the mass of the entire molecule.
Explanation:
This is actually fairly straight-forward.
You know that
You also know how much a mole of
So the question really is, what % of the mass of a mole of
That would be the total mass of nitrogen, 2 x 14.007 divided by 108.011, and multiplied by 100%.
