1.

Three solution are prepared by adding "wg" of "A" into 1kg of water , 'w' g of B into 1kg of water and 'w' g of c into 1kg of water (A, B, C, are non electrolytic). Dry air is passed from these solutions in sequence (A rarr B rarr C) . The loss in weight of A was found to be 2gm while solution B gained 00.5 gm and solution C lost 1gm then the relation molar masses of A, B and C is :

Answer»

`M_(A):M_(B):M_(C)=1:2:3`
`P_(SA):P_(SB):P_(SC)=5:3:1`
`M_(A) GT M_(A) gt M_(C)`
`M_(B) gt M_(A) gt M_(C)`
