mols of gas per metre cubed

[bigjimlad]

Hi,



This is probably very simple, but the result is quite important for what I'm doing so I need to be sure it's right.

I need to know how many mols of gas there are in a metre cubed, say at atmospheric pressure and temperature.



If I use pV = nRT where

p = 110kPa

V = 1m

R = 8.314

T = 273 K,



Then I work this out as 44.5 mols/m^3



Does this seem like a sensible answer?
