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
mal wt is 120) could be -
​

Answer 1

Atomic weight of X =30 and Y =20

Molecular weight of that compound  = 120

Hence, the Molecular formula of that compound is X2Y3  

( 2*30+ 3*20 = 60+60=120)
