    Iron: % by mass= 69.9 Atomic mass= 55.85 Moles of element( relative no. of moles)= 69.9/55.85 = 1.25 Simplest molar ratio = 1.25/1.25 = 1 Simplest whole no. molar ratio= 2 Oxygen: % by mass = 30.1 Atomic mass = 16.00 Moles of element =30.1/16.00 = 1.88 Simplest molar ratio = 1.88/1.25 = 1.5 Simplest whole no. molar ratio = 3 Fe2O3
