The time taken for a certain volume of gas to diffuse through a small hole was . Under similar conditions an equal volume of oxygen took minute to pass. The molecular mass of the gas is
View answer and explanation
Correct option: C
Option C (4.0) is correct because it is calculated using Graham's law of diffusion, relating the rate of diffusion to the square root of the molar mass.
