# How would you find the volume (in liters) of 7 moles of CH_4 at standard temperature and pressure (0 deg celsius and 1atm)?

At $\text{STP}$, $1$ mole of Ideal gas occupies a $22.4 \cdot L$ volume.
Given this information, if there are $7$ $\text{moles}$ of methane, the volume is simply the product:
$7 \cdot m o l \times 22.4 \cdot L \cdot m o {l}^{- 1}$ $=$ ??L.
