An unknown compound has the following chemical formula: nox where x stands for a whole number. measurements also show that a certain sample of the unknown compound contains 7.5 mol of oxygen and 7.5 mol of nitrogen. write the complete chemical formula for the unknown compound.

Because the species are in equimolar amount, they must also be the same in the compound. Thus, the formula is:
NO
