Two vessels A and B contain the same ideal gas. The volume of B is twice that of A, the pressure in B is twice that in A and the temperature of B is twice that of A. The ratio of the number of gas molecules in A and B is

A

`1:2`

B

`2:1`

C

`1:4`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
a
`"Number of moles in A is, "n_(A)=(PV)/(RT)`
`"Number of moles in B is, "n_(B)=((2P)(2V))/(R(2T))=2n_(A)`
`n_(A):n_(B)=1:2`
