A current is passed through two cells connected in series. The first cell contains X`(NO_(3) )_( 3)` (aq) and the second cell contains Y`(NO_(3) )_( 2)` (aq). The relative atomic masses of X and Y are in the ratio `1: 2`. What is the ratio of liberated mass of X to that of Y?

A

`3:2`

B

` 1:2`

C

`1:3`

D

` 3:1`

Text Solution

Verified by Experts

The correct Answer is:
C
If atomic mass of x=a, then that of y=2a
`therefore` Eq. mass `=("at. Mass")/("valency")`
`therefore` Eq. mass of `x=a//3`. Eq mass of
`y=2a//2=a`.
`("Mass of x")/("Mass of y")=("Eq. mass of x")/("E q mass of y")`
`=(a//3)/(1)=(1)/(3)= 1:3`
