PV = nRT
You know P. Assume V = 1 L. You know R and T. Calculate n = mols and that is mols in 1 L.
mols = g/molar mass. you now know mols and you know molar mass. Calculate grams. And that is in 1 L so the answer is g/L. You can do it another way all in one step if you want to redo the equation a little.
PV = nRT
P = (n/V)*RT
but n = g/molar mass so
P = (g/molar mass*V)*RT
But g/V = density = d so
P = (d/molar mass)*RT and solve for d.
d = (P*molar mass)/(RT)
