Question

How fast does ethane(C2H6)) gas travel compare to chlorine gas

Answer 1

First of all write the molar masses of Gases,

Molar Mass of Cl₂ = 71 g/mol

Molar Mass of Ethane = 30 g/mol

According to Graham's Law of Diffusion,


`(Rate of diffusion of Light Gas)/(Rate of Diffusion of Heavy Gas)` =
`√(M.mass of Heavy / M.mass of Light)`


`(Rate of diffusion of Light Gas)/(Rate of Diffusion of Heavy Gas)` =
`√(71 g/mol / 30 g/mol)`


`(Rate of diffusion of Light Gas)/(Rate of Diffusion of Heavy Gas)` =
`√(2.366)`


`(Rate of diffusion of Light Gas)/(Rate of Diffusion of Heavy Gas)` = 1.53

Result:
So, Ethane gas will diffuse or move 1.53 time faster than Chlorine gas.
