Two separate bulbs contain ideal gas `A` and `B`. The density of a gas `A` is twice that of a gas `B`. The molecular mass of `A` is half that of gas `B`. The two gases are at the same temperature. The ratio of the pressure of `A` to that gas `B` is

A

2

B

`1//2`

C

4

D

`1//4`

Text Solution

Verified by Experts

The correct Answer is:
c
(c) `PMw=dRT`
`(P_(A))/(P_(B))=(d_(A))/(d_(B))xx(M_(B))/(M_(A))`
` =(4)/(1)`
