Holy fuck I'm an idiot and I don't know how to do this calculation

"Elemental analysis Found values for
carbon, hydrogen, and nitrogen (if present) should be within 0.4%"

How do I determine whether two values (theoretical and experimental) are within 0.4 % of each other? I'm doing the regular (T-E)/T x 100, but it doesn't seem to be consistent with the info my teacher is telling me.

The problem is trivial.
Think about molar mass.

Thanks for the help, but I still don't follow. Is the calculation I mentioned in the OP completely wrong? Please excuse my idiocy.

You shouldn't need it, think about the number of bonds a Carbon/Nitrogen can form and what that means.
