Solution

Valency is the combining capacity of an element.
The negative radical present in the salt is silicate (SiO₃)^-2. It is a bivalent radical.
The positive radicals present in Y are A⁺³(trivalent) and B⁺ (monovalent).
In a chemical compound the total positive charges is same as the total negative charges. The compound is electrically neutral.
Therefore, the formula of Y is BA(SiO₃)₂.
The number of atoms of each element in Y is A=1, B=1, Si=2, O= 3x2 =6
One molecule of Y contains 6 oxygen atoms.
