Helium diffuses 4 times faster than an unknown gas under similar conditions. Find the vapour density of unknown gas. |
|
Answer» SOLUTION :RATIO of rates of diffusion of helium and unknown gas is given as, `(r_(1))/(r_(2)) = sqrt((VD_(2))/(VD_(1))) (or) (4)/(1) = sqrt((VD_(2))/(2))` `VD_(2) = 2xx 4^(2) = 32` vapour density of unknown gas = 32 |
