The molecular weight of a gas which diffuses through a porous plug at `1//6^(th)` of the speed of hydrogen under identical condition is:

A

27

B

72

C

36

D

48

Text Solution

Verified by Experts

The correct Answer is:
C
`r_(X)/r_(H_(2))=sqrt((M_(H_(2)))/M_(X)),(1)/(6)=sqrt((2)/(M_(X))),M_(X)=72`
