Explanation:
We assume ideality, and we know that
And so
And so
And so we plug in the numbers....
The density is
Explanation:
The molar mass of
We can use the Ideal Gas Law to determine its density.
#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#
Since
#pV = (m/M)RT#
We can rearrange this to
#pM = m/VRT#
But
∴
and
#color(brown)(bar(ul(|color(white)(a/a)ρ = (pM)/(RT)color(white)(a/a)|)))" "#
In your problem,
∴
