Question

h2 gas effuses from a 1 dm cube in 10 second calculate the time for a effusion of O2 gas from 20 dm cube vessel.​

Answer 1

Answer:

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∝

r=rate of diffusion

M=molar mass
