The ratio of the vapour densities of two gases at the same temperature is `8:9`. The ratio of the rms velocities of their molecules is

`8:9`

`9:8`

`sqrt(9):sqrt(8)`

`sqrt(8):sqrt(9)`

Text Solution

Verified by Experts

The correct Answer is:

`(C_1)/(C_2) = sqrt((rho_2)/(rho_1)) = sqrt(9/8)` .
