The percentage of an element M is 53 in its oxide of molecular formula M2O3 . Its atomic mass is about 27.
Let the mass of oxide be 100
∴∴ mass of element m is 53
Mass of oxygen is 100-53=47
∴∴ Equivalent mass of element = Mass of element / Mass of oxygen × 8
= 53/47 × 8
=9(approx)
∴∴ Atomic mass=Equivalent mass×valency
⇒9×3
