its quite simple if you go by a simple method of finding density at STP
we know that mas of
and one mole of
and we also know that the volume of one mole of any gas is 22.4
upon substitution with the formal equation of density we get .
The density of
Yes, there is a gas law equation for density.
It is a variation of the Ideal Gas Law.
we can write
#ρ = (pM)/(RT)#
STP is defined as 1 bar and 0 °C.
In this problem,
