We know vapour density =Molecular weight/2
and Molecular weight=(AB2)n
n is number
vapour density=n/2(AB2)=(AB2)
so n=2
so Molecular formula=A2B4
B) (AB)n/2=(AB)3
n=6
so A6B6 is Molecular formula
and Molecular weight=(AB2)n
n is number
vapour density=n/2(AB2)=(AB2)
so n=2
so Molecular formula=A2B4
B) (AB)n/2=(AB)3
n=6
so A6B6 is Molecular formula
