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_(H_(2))/(r_(X)) = 6`
`(r_(H_(2)))/(r_(X)) = sqrt((M (X))/(M(H_(2))))`
`6 = sqrt((M(X))/(2))`
`M(X) = 72 g mol^(-1)`
