# A 3.4 g sample of carbon dioxide (CO_2) gas is confined to a 450 mL rigid container at 55 deg C. How can you determine the pressure in the container?

Use the Ideal Gas Law, $P = \frac{n R T}{V}$
$P = \frac{3.4 \cdot g}{44.0 \cdot g \cdot m o {l}^{-} 1} \times \frac{0.0821 \cdot L \cdot a t m}{K \cdot m o l} \times 328 \cdot K \times \frac{1}{0.45 \cdot L}$
$\cong$ $5 \cdot a t m$
