At room temperature, the rms speed of the molecules of a certain diatomic gas is found to be 1930m/s. The gas is

A

`H_2`

B

`F_2`

C

`O_2`

D

`CI_2`

Text Solution

Verified by Experts

The correct Answer is:
A

`v_("rms")=sqrt((3RT)/(M))`
Room temperature, `T~~300K`
`1930=sqrt((3xx8.31xx10^(3)xx300)/(M))`
`M=2g`
or the gas is `H_(2)` .
