Iron = 69.9% , dioxide = 30.1%

Atomic Mass of Fe = 55.85

Atomic mass of O = 16

Mole of Oxygen =   $\fn_cm&space;\frac{%&space;of&space;di&space;oxide&space;}{atomic&space;mass&space;of&space;oxygen}&space;=&space;\frac{30.1&space;}{16}&space;=&space;1.88$

Mole of fe  = $\fn_cm&space;\frac{%&space;\:&space;of&space;\,&space;Fe}{Atomic\,&space;mass&space;\,&space;of&space;\:&space;oxygen}&space;\,&space;=&space;\,&space;\frac{69.9}{55.85}&space;\,&space;=&space;\,&space;1.25$

Molecular ratio in ratio simplest form = 2 : 3
