# How many molecules of CO_2 are there in a molar quantity of this gas?

Jun 7, 2016

Well, in $1$ $\text{mole}$ of stuff there are $6.022 \times {10}^{23}$ individual items of stuff.

#### Explanation:

$\text{Number of moles}$ $=$

$\left(9.3 \times {10}^{24} \cdot \text{molecules of "CO_2)/(6.022xx10^23*"molecules of } C {O}_{2} \cdot m o {l}^{-} 1\right)$

$=$ ??mol

What is the mass of this quantity of $C {O}_{2}$?
