Question

5 mL of He gas diffuses out in 1 second from a hole. Find the volume of SO2

that will diffuse out from the

same hole under identical conditions in 2 seconds.​

Answer 1

Answer:

14.4 ...

Explanation:

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
