# What is the volume occupied by 25.2 g of CO_2 at .84 atm and 25°C?

Approx...$17 \cdot L$
We solve for $V$ in the Ideal Gas equation...
$V = \frac{n R T}{P} = \frac{\frac{25.2 \cdot g}{44.01 \cdot g \cdot m o {l}^{-} 1} \times 0.0821 \cdot \frac{L \cdot a t m}{K \cdot m o l} \times 298 \cdot K}{0.84 \cdot a t m}$
