Dear Student,

Equivalent mass=Atomic massValencyOr, Atomic mass=Equivalent mass×ValencyIn M2O3, total charge or valency on M is +3and, Equivalent mass of metal=mass of metalmass of oxygen×8=1312×8=8
66Therefore, Atomic mass of M=8
66×3≈26

In the metal oxide M2O3, ratio between the masses of metal and oxygen is 13:12. Calculate the atomic mass of the metal.
