Hydrogen diffuses six times faster than ...

Hydrogen diffuses six times faster than the gas A. The molar mass of gas A is

A

72

B

6

C

24

D

36

Text Solution

Verified by Experts

The correct Answer is:
A
`(r_(H))/(r_(A))=sqrt((M_(A))/(M_(H)))rArr6=sqrt((M_(A))/(2))`
`rArr` `36=(M_(A))/(2)rArrM_(A)=72`
