Oxygen is available in divalent form.
But with 3 oxygen atoms presence present in M2O3, it is clearly evident that M atoms are signifying the presence of electron.
The valency of M2O3 is 3.
And it forms M2 (SO4)3 with sulphate and MBr3 with Bromine.

HEY....☺
Here's ur ans. ⤵
_________________
Valency of M is 3
M. O
2. 3
We cross multiply to find valency of an element in any compound or molecule I.e. the valency of O is 2 and M is 3
Its SULPHATE --- M2 ( SO4)3
Its BROMIDE -- M (Br)3
