Iron oxide has most often has 2 atoms of iron per molecule.
There are two forms of iron oxide, FeO (which has one iron atom) and Fe2O3.
Iron can take on a valence of II or III. Confusing. There are actually addition formulas for other iron oxides, too, including magnetite (Fe3O4).
The most common form is the Fe2O3 structure, which is the familiar iron rust.

A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.
Well, iron oxide is a combination of iron(Fe) and oxygen (O). We know Fe(III) has a charge of +3 and oxygen has a charge of -2, so we must balance them. Their LCF is 6, so to balance them, we must have 2 atoms of iron (3x2=6) and 3 atoms of oxygen (-2x3=-6). Therefore we know that there are 2+3 atoms in this molecule, so 6 atoms in the molecule.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
Iron oxides are inorganiccompounds.
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%

yes
Rust (Iron-III oxide) is an ionic compound formed from iron atoms and oxygen atoms. We don't refer to an ionic solid as being a molecule, though, we represent the solid by its smallest building block. In this case, we represent iron (III) oxide as Fe2O3.
The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.

When two oxygen atoms react together they form an oxygen molecule (O2).
Since iron oxide is made from TWO elements (Fe, and O), it is a compounds and so you have a MOLECULE, not an atom of iron oxide.
