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.

Iron can form two different oxides, ferric oxide Fe2O3 (5 atoms) and ferrous oxide Fe3O4 (7 atoms)
There are two iron atoms in iron III oxide.
Iron has many oxides; Fe2O3 has two Fe atoms.
Iron oxide is Fe2O3.

Iron II oxide: FeO Iron III oxide: Fe2O3
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
The chemical formula Fe2O3 is for the chemical compound known as Iron(III) oxide. Its melting point is 2,851 degrees Fahrenheit.
Iron (III) Sulfide Ferrous Sulfide
A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.
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.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
In chemical equations, two molecules of iron (III) oxide, sometimes alternatively called ferric oxide.
The name of the compound Fe3O4 is called iron (II,III) oxide. (Wikipedia)
When iron is burnt (heated) and exposed to air the iron will combine rapidly with oxygen atoms to form FeO molecules (FeO - Iron Oxide - Also known as 'rust' on iron materials)
iron (III) oxide
250 g iron (III) oxide is equal to 1,565 moles.
It stands for the charge on the iron ion. In Iron III oxide iron has a 3+ charge.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
Depend on it's valence state. Iron is transition metal and had many possible valence state (e.g. Fe2+ or Fe3+). For the case Fe2+ then it is just FeO and 1 atom informula but if it is Fe3+ then it is Fe2O3 and thus 2 atoms. You must check what written clearly, for iron oxide such as rust, it is wrtten as iron(III)oxide to stand for being a Fe3+.
The preparation of iron(III) oxide is simple.
