There are $24 \cdot m o l$ of atoms in $8 \cdot m o l$ of $C {O}_{2}$....

#### Explanation:

Before we do this in detail, let us suppose that the question asked....$\text{find the number of atoms in 8 DOZEN molecules of}$ $C {O}_{2}$.

And thus, there are $3 \cdot \text{atoms}$$\cdot {\text{molecule}}^{-} 1$ $\times 8 \times 12$ $\text{molecules}$

$= 3 \times 8 \times 12 = 288 \cdot \text{atoms}$

The question asked here is ENTIRELY ANALOGOUS EXCEPT that instead of $\text{dozens}$ we use $\text{moles}$ where $1 \cdot \text{mole of stuff}$ $\equiv$ $6.022 \times {10}^{23} \cdot \text{individual items of stuff}$.

And thus there are $8 \times 6.022 \times {10}^{23} \cdot \text{atoms}$

$\cong 48 \times {10}^{23} \cdot \text{atoms}$
