# A molar volume of gas whose mass is 222*g*mol^-1 is confined in a 22.4*L container. What is the density of the gas in g*L^-1?

At $\text{STP}$, one mole of ideal gas occupies occupies a volume of $22.4 \cdot L$. So.......
$\rho , \text{density"="Mass"/"Volume}$.
$\rho = \frac{222 \cdot g \cdot m o {l}^{-} 1}{22.4 \cdot L \cdot m o {l}^{-} 1} \cong 10 \cdot g \cdot {L}^{-} 1$.
