There are at least 2 (or 3) different Iron oxide molecules: FeO, Fe2O3, (Fe3O4)
From them you can add up althe atom's subscripts to get the total number of atoms:
respectively 1+1=2, 2+3=5, (3+4=7)
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
a. 1 iron atom per molecule. in total, two atoms
If 8 atoms of iron react with 6 molecules of oxygen, they will form 4 units of iron oxide (Fe2O3) because each molecule of iron oxide contains 2 atoms of iron and 3 atoms of oxygen.
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+.
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.
5 atoms; 2 of Iron and 3 of Oxygen
5 atoms; 2 of Iron and 3 of Oxygen

A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.
One formula unit of gallium oxide (Ga2O3) contains a total of 5 atoms - 2 gallium atoms and 3 oxygen atoms.
