# What pressure, in atmospheres, is exerted by 0.325 mol of hydrogen in a 4.08 L container at 35^o C?

Approx. $2.0 \cdot a t m$
$P = \frac{n R T}{V}$
$\frac{0.325 \cdot \cancel{m o l} \times 0.0821 \cdot \cancel{L} \cdot a t m \cdot \cancel{{K}^{-} 1} \cdot \cancel{m o {l}^{-} 1} \times 308 \cdot \cancel{K}}{4.08 \cdot \cancel{L}}$ $=$ ??atm
