what is the total # of molecules in 4Fe2O3 (small 2 and 3)?

Answer 1

Four molecules of Fe2O3.

Iron(III) oxide or ferric oxide (Fe2O3): known in its natural state as rouge or hematite (also 'haematite'), but also purified for use as a coating in magnetic audio and computer media, where it is known as ferric oxide. In a dry or alkaline environment it can cause passivation and inhibits rust. It is also a component of rust.

Answer 2

The 4 indicates that there are four Iron Oxide molecules.

4 x Fe2O3

The Fe2 means two ATOMS of Iron. The O3 means three ATOMS of Oxygen and, together they make ONE MOLECULE.

The answer: Total Molecules = 4

Answer 3

Four molecules of iron(iii) oxide.

This contains in total 8 iron atoms and 12 oxygen atoms,making a total of 20 atoms.

Is this what you wanted to know?

Answer 4

4 the molecules are Fe2O3 5 atoms each. they like to ask both questions atoms or molecules.
