The ratio, `("rms velocity of" SO_(2))/("rms velocity of He")`, of sulpur dioxide and helium gases at `30^(@)C` is equal to:

A

`4`

B

`0.25`

C

`0.10`

D

`8`

Text Solution

Verified by Experts

The correct Answer is:
B
`((U_(rms))SO_(2))/((U_(rms))_(He))=sqrt((M_(He))/(M_(SO_(2))))`
`sqrt((4)/(64))=(1)/(4)= 0.25`
