A level Physics(ideal gas) question?

The density of nitrogen at s.t.p = 1.251 kg/m^3 .

Calculate the r.m.s velocity of nitrogen molecules.

Show your working...

Thanks : )

I beg your pardon, but what's rms? Laughing

I think I've forgotten.

erm...

from your other thread,

p = (1/3)(Nm/V)<c²>
p = (1/3)(density)<c²>

At s.t.p, so p = 1.013*10^5
so <c²> = 242925.6

r.m.s. = 492.9 m/s

Do check, might have some careless mistakes
