At room temperature, the rms speed of the molecules of a certain diatomic gas is found to be `1930 m//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_(" m s ") = sqrt((3RT)/M)`
Room temperature, `T ~~ 300 K `
`1930 = sqrt((3xx8.31 xx10^3 xx300)/M)`
` M = 2g`
or tha as is `H_2`
