Find out the rms speed of nitrogen gas molecules at `0^@C`. The density of nitrogen gas at STP=`1.25 g.L^-1`
and density of mercury =`13.6 g.cm^-3`

Text Solution

Verified by Experts

`p=76 times 13.6 times 980 dyn.cm^-2`
`p=1.25 g.L^-1=1.25 times 10^-3 g.cm^-3`
rms speed, `c=sqrt((3p)/p)`
`=sqrt((3times(76times13.6times980))/(1.25times10^-3))`
`=4.93times10^4 cm.s^-1`
