At room temperature the rms speed of the molecules of a certain diatomic gas is formed to be `1930m//sec` The gas is .

A

`H_2`

B

`F_2`

C

`O_2`

D

`Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(rms)=sqrt((3RT)/(M)) implies M = (3RT)/(v_(rms)^2)=(3xx8.31xx300)/((1920)^2)`
`=2 xx 10^(-3)` kg 2g `implies` Gas is hydrogen
