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_(2)))/(r_(A)) = sqrt((M_(A))/( M_(H_(2))) )` or `6 = sqrt((M_(A))/( 2))`
`:. M_(A) = 72u`.
