4Fe + 3O2 = 2Fe2O3

So in math book it say " You can interpret this equation in terms of representative particles by saying that four atoms of iron react with three molecules of oxygen to produce two formula unit of iron(iii) oxide"

Why it say that there are 4 atoms of iron / 3 molecules of oxygen and 2 formula unit of iron3 oxide? Don't a mol of anything have 6.02E23 representative particle? Won't there be 4(6.02E23) atoms of iron / 3(6.02E23) molecules of oxygen and 2(6.02E23) formula unit of iron3 oxide? Thanks
