We rearrange the Ideal Gas Equation............and get $ρ ≅ 0.9 \cdot g \cdot L^{- 1}$ $rho~=0.9*g*L^-1$

Explanation:

$P V = n R T$ $PV=nRT$ , which equation is this?

So $\frac{P V}{R T} = n = \frac{Mass}{Molar Mass}$ $(PV)/(RT)=n="Mass"/"Molar Mass"$

And thus, $\frac{Molar Mass \times P}{R T} = \frac{Mass}{V}$ $("Molar Mass"xxP)/(RT)="Mass"/V$

But $\frac{Mass}{V} = ρ (density)$ $"Mass"/V=rho"(density)"$

And thus $ρ = \frac{Molar mass \times P}{R T}$ $rho=("Molar mass"xxP)/(RT)$

And now we plug in the values.........

$ρ = \frac{44.01 \cdot g \cdot m o l^{- 1} \times 0.50 \cdot a t m}{0.0821 \cdot \frac{L \cdot a t m}{K \cdot m o l} \times 300 \cdot K} = ? ? \cdot g \cdot L^{- 1}$ $rho=(44.01*g*mol^-1xx0.50*atm)/(0.0821*(L*atm)/(K*mol)xx300*K)=??*g*L^-1$
