Helium and argon are monoatomic gases and their atomic weights are 4 and 40 respectively. Under identical conditions, helium will diffuse through a semipermeable membrane

A

3.16 times as fast as argon

B

7.32 times as fast as argon

C

1.58 times as fast as argon

D

10 times as fast as argon.

Text Solution

Verified by Experts

The correct Answer is:
A
`(r_(He))/(r_(Ar)) = sqrt((M_(Ar))/(M_(He))) = sqrt((40)/(4) = sqrt(10) = 3.16`
