# What is the density of a gas whose mass is 0.80*g, and which is confined to a 560*cm^3 volume?

$\text{Density}$, $\rho$ $=$ $\text{Mass"/"Volume}$ $=$ $1.4 \times {10}^{-} 3 \cdot g \cdot c {m}^{-} 3$
$\rho = \frac{0.80 \cdot g}{560 \cdot c {m}^{3}} = 1.4 \times {10}^{-} 3 \cdot g \cdot c {m}^{-} 3$.
