Question

0.2 mole of oxygen gas was effused through a porous plug in 300 seconds at STP. Calculate the volume of hydrogen effused at the same time and in identical condition. ​

Answer 1

Explanation:

Correct option is C)

Given,

Time taken for oxygen diffusion=10 sec

Also pressure,volume,temperature is constant.

Molar mass of oxygen=32g/mole

Molar mass of sulphur dioxide=64g/mole

According to graham's law of diffusion/effusion

r∝

M

r=rate of diffusion

M=molar mass
