The density of gas A is twice that to B ...

The density of gas A is twice that to B at the same temperature. The molecular weight of gas B is twice that of A. The ratio of pressure of gas A and B will be :

`1:6`

`7:8`

`2:5`

`1:4`

Text Solution

Verified by Experts

`Pm=dRT`
`(P_(A)m_(B))/(P_(B)m_(B))=(d_(A)RT)/(d_(B)RT)`
`(P_(A))/(B_(B))xx(1)/(3)=2`
`P_(A):P_(B)=6:1`
