If the density of hydrogen gas at N.T.P. is `8.93xx10^(-5)gm//cm^(3)` then the rms speed of the molecules of the hydrogen gas at NTP will be

A

1840 cm/s

B

184 m/s

C

1840 m/s

D

18.4 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
`C=sqrt((3RT)/(M))=sqrt((3RT)/(M))=sqrt((3P)/(rho))`
`=sqrt((3.039xx10^(6))/(8.93xx10^(-5)))=sqrt((3.039)/(8.93))xx10^(5)`
=1840 m/s
