The rms speed of hydrogen molecules at S...

The rms speed of hydrogen molecules at STP is `1.85 km.s^-1` What is the density of hydrogen gas?

Text Solution

Verified by Experts

Here, `c=1.85 km.s^-1 =1.85 times 10^5 cm.s^-1`,
`p=76 times 13.6 times 980 dyn.cm^-2`
From the equation `p=1/3 pc^2` we get,
`p=(3p)/c^2=(3times(76times13.6times980))/((1.85times10^5)^2)`
`=0.000089 g.cm^-3`
