An exploding (at the end of its life) star. Same for all the other atoms - except hydrogen.

Iron is a metal and does not consist of molecules. The number of atoms of iron in one mole is 6.022 x 1023.
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
Either one. This is incorrect. The correct answer would be that it is made of separate atoms because iron is an element or a pure substance. So, therefore it didn't combine with anyother atoms to form a molecule and that being said it is strictly made up of separate atoms and not molecules. Definitely not either one.
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.

They are not formed in the body. Iron is a mineral and is also an element. It occurs in nature and we get iron into our bodies by ingestion. Usually the best sources for iron are green leafy vegetables, legumes, meats, and multivitamins with minerals.
the mineral is IRON
The molecules of iron combine with molecules of oxygen to form molecules of iron oxide- or rust.

Metals haven't molecules.

Probably you mean Iron and Oxygene atoms? It is a mix of oxides Fe2O3*FeO.
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
Red blood cells contain the substance haemoglobin, which is an iron-based molecule that binds to oxygen molecules for transport around the body.
Iron is necessary to carry oxygen molecules to your cells.
