# What is an example of a molar volumes of gases practice problem?

Jun 21, 2018

Under standard conditions, a gas occupies $29 \cdot L$; what is the molar quantity of the gas?

#### Explanation:

Of course, the question will specify the standard conditions, and also quote the molar volume of a gas under same conditions. Typically, under standard conditions of $1 \cdot \text{bar}$ and $298 \cdot K$, such volume is $24.8 \cdot {\mathrm{dm}}^{3} \cdot m o {l}^{-} 1$...

...and here $1 \cdot {\mathrm{dm}}^{3}$, a unit of VOLUME is...

$1 \cdot {\mathrm{dm}}^{3} \equiv {\left(1 \times {10}^{-} 1 \cdot m\right)}^{3} = {10}^{-} 3 \cdot {m}^{3} \equiv 1 \cdot L$...

i.e. $1 \cdot L \equiv 1 \cdot {\mathrm{dm}}^{3}$...

If you want more such examples, perhaps you should specify at which level you study...
