1.	.A compound of X and Y has equal mass of thenIf their atomic weights are 30 and 20 respectiveMolecular formula of that compound(2) X,Y3(4) XY(3) XY13.
Answer» both the compound zn and Ca have valency 2, so theit molecular formula will be X2Y2 wrong ans. what is the answer then?? x2y3 Given the compounds have equal mass of them in a formulasuppose the mass is M so , no. of moles for X = M/30and for Y = M/20 so x/y = 2/3 from above the molecular formula will be X2Y3

Answer»

both the compound zn and Ca have valency 2, so theit molecular formula will be X2Y2

wrong ans.

what is the answer then??

x2y3

Given the compounds have equal mass of them in a formulasuppose the mass is M so , no. of moles for X = M/30and for Y = M/20

so x/y = 2/3

from above the molecular formula will be X2Y3
