One male of nitrogen gas at `0.8` atm takes 38 seconds on diffuse through a pinhole, whereas one mole of a compound of xenon with fluorine at 1.6 atm takes 57 secondes to diffuse through the same hole. Calculate molecular weight of the compound.

Answer

`00252.00`

Explanation

`00252.00`
`(r_(1))/(r_(2))=sqrt((M_(2))/(M_(1)))xx(P_(1))/(P_(2))`
or `(n_(1))/(t_(1))xx(t_(2))/(n_(2))=sqrt((M_(2))/(M_(1)))xx(P_(1))/(P_(2))`
or `1/38xx57/1=sqrt(M/28)xx0.8/1.6`
`:. M=252`
