One mole is an elementary unit of measurement. It consists of 6.022*10^23 elementary particles. For example a mole of sodium has 6.022*10^23 sodium atoms while one mole of sodium chloride has 6.022*10^23 molecules of sodium chloride.
The elementary unit in the case of Fe2O3 has 2 atoms of iron and 3 atoms of oxygen.
6 moles of Fe2O3 have 6*2*6.022*10^23 atoms of iron.
This is equal to 72.264*10^23 atoms of iron.

My calculator gets 7.2264*10^24. . .
