Say you have 1 mole, or 108 grams of the compound.
The ratio says that for every 9 grams of Carbon, you have 1 gram of Hydrogen and 3.5 grams of Nitrogen. Sum this up and you get 13.5 grams - how convenient, it’s a factor of 108!
So now we multiply everything by 10813.5\equals810813.5\equals8 and we get 72 grams of Carbon, 8 grams of Hydrogen, and 28 grams of Nitrogen.
Divide those numbers by molar masses and you get 6 moles of Carbon, 8 moles of Hydrogen, and 2 moles of Nitrogen per mole of the compound.
In other words:
C6H8N2C6H8N2
which can be many compounds but you’re not required to find the structure.
