Hydrogen diffuses six times faster than ...

Hydrogen diffuses six times faster than 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_(A))/(r_(H)) = sqrt((M_(H))/(M_(A))) = (r)/(6r) = sqrt((2)/(M_(A)))`
`M_(A) = 6 xx 6 xx 2 = 72 `g
