# What volume will 3.4 g of CO_2 occupy at STP?

Apr 2, 2018

$\approx 1.755 \setminus \text{L}$

#### Explanation:

At $\text{STP}$, a gas will contain approximately a volume of $22.7 \setminus \text{L}$. Click here for the explanation.

So here, we need to convert $3.4 \setminus \text{g}$ of carbon dioxide into moles.

Carbon dioxide has a molar mass of $44 \setminus \text{g/mol}$. So here, there exist,

(3.4color(red)cancelcolor(black)"g")/(44color(red)cancelcolor(black)"g""/mol")=0.0772727273 \ "mol"

And so, the molar volume is:

$0.0772727273 \textcolor{red}{\cancel{\textcolor{b l a c k}{\text{mol"*(22.7 \ "L")/(color(red)cancelcolor(black)"mol")=1.75409090971 \ "L}}}}$

$\approx 1.755 \setminus \text{L}$
