A compound of X and Y has equal mass of them. If their atomic weights

1.	A compound of X and Y has equal mass of them. If their atomic weights are 30 and 20 respectively. Molecularula of that compound (its mol wt.is 120) could be :(2) x3Y3(3) X2Y3(4) х,у,
Answer» Atomic weight of X =30 and Y =20Molecular weight of that compound = 120 Hence, theMolecular formula of that compound is X2Y3 ( 230+ 320 = 60+60=120)

Answer»

Atomic weight of X =30 and Y =20Molecular weight of that compound = 120

Hence, theMolecular formula of that compound is X2Y3

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