Magnetite, which has the formula Fe3O4, is comprised of iron(II) oxide and iron(III) oxide. What is the ratio of iron(II) ions to iron(III) ions in magnetite?
The answer is 1:2, but I fail to see how that's the answer. Isn't Fe3O4 also known as Fe2O3*FeO? so I figured that the ratio must be 1:1, but it's not. Where's the flaw in my logic?
