Question

a compound of X and Y has equal mass of them.if their atomic weights are 30 and 20 respectively.molecular formula of that compound will be​

Answer 1

x,y are coumponds

let weight=v

molecular weight of x = (moles)=wt/gmw

=v/30

molecular weight of y=

moles=wt/gmw

=v/20

molecular weight= moles *NA(avagadro number)

molecular weight=v* 20*Na/v*30*Na

= 20/30 =2/3

= x2y3
