The molecular weight of a gas which diffuse through a porous plug of 1/6th of the speed of hydrogen under identical conditions is:
View answer and explanation
Correct option: B
72
Option B (72) is correct because the molecular weight is calculated using Graham's law of diffusion, relating the rates of diffusion to the square root of their molecular weights.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases
