    There are two iron atoms and three oxygen atoms in each molecule of Fe2O3. So that's five atoms per molecule. One mole of any molecular substance contains 6.02*1023 molecules. Since there are two iron atoms in each of the molecules we're considering, there will be (6.02*1023) ⋅2=1.204*1024 iron atoms in a whole mole of them. But we're considering 0.550 mol, so multiply by 0.550:n = (0.550 mol) ⋅ (3.01*1024 atoms/mol) = 6.62*1023 iron atoms.
