O2
Fe3O2. But it's not right! Oxygen forms a 2- ion and iron can be 2+ or 3+. So the formulae of iron oxide can be FeO or Fe2O3.
The chemical formula for sodium ethanoate is NaC2H3O2. Its molecular formula is CH3COONa. It can also be written as NaCH3COO.
Sulfur undergoes many reactions with oxygen, leading to the formation of sulfur oxides; these can have a variety of formulae. Sulfur + oxygen ---> sulfur DIoxide. This is the balanced equation of the above reaction: S + O2 ---> SO2
Hydrogen peroxide is H2O2 For more information see related link.
We usually don't see a nitrogen atom change into an oxygen atom. This kind of change is a nuclear transmutation, and we just don't encounter much of this nitrogen-to-oxygen thing happening in nature. But there are instances where nitrogen can "change" into oxygen, and we have to look at a couple of isotopes of oxygen and nitrogen to discover if a nuclear reaction might transform nitrogen to oxygen. Let's take a little trip through an operating pressurized water nuclear reactor where this actually happens.The water circulating in a water-cooled nuclear reactor is H2O, and you knew that. Most of the oxygen in that water is oxygen-16. When water passes through the core of the reactor, the high neutron flux can activate the oxygen. An oxygen-16 atom can absorb a neutron and then undergo beta decay to become nitrogen-16. Further, nitrogen-16 in the water can then absorb a neutron and become nitrogen-17. It turns out this happens a lot. But the nitrogen-17 is very unstable, and it transforms via beta decay back into oxygen. The oxygen-17 on the end of this series of transformations is stable, by the way. But it will cycle back through the reactor and may undergo more transformations.A link can be found below to a related question, and the curious investigator might wish to trace the transformations mentioned. Further, a hard-core learner might want to come up with the nuclear formulae that are written to express the reactions.
o2
The element, 'Oxygen' is abbreviated to 'O'.
Hydrogen gas is H2. Oxygen gas is O2.
The formula for water is H2O. The molecule is formed from one atom of oxygen and two atoms of hydrogen.
What are the conventional formulae?
There are thousands of mathematical formulae.
The formulae for potassium nitrate is 'KNO3' This tells us that there is one atom of potassium , one atom of nitrogen and three atoms of oxygen. #So yes!!! there is oxygen present in potassium nitrate.
You will find several formulae in the Wikipedia article on "derivative".

Mainly, many magnitudes are related through different kinds of formulae. In advanced science you may have to derive your own formulae, but in more basic science, you just use existing formulae.Mainly, many magnitudes are related through different kinds of formulae.
