From a porous vessel containing equimolar proportions of hydrogen and oxygen, the composition by mass of the mixture effusing out is `:` hydrogen and oxygen in the ration of

Options

A. `1:4`
B. `2 sqrt( 2) : 1 `
C. `1: 2 sqrt(2)`
D. `4:1`

Answer

D

Explanation

`( "Rate of effusion of " H_(2))/( "Rate of effusion "O_(2)) = ( " Mass" ( H_(2))//t) /( "Mass" ( O_(2))//t) = sqrt((32)/( 2))`
`("Mass of " H_(2))/( "Mass of " O_(2)) = ( 4)/(1)`
or `4:1`
