You know, I could replace $\text{moles}$ by $\text{dozens}$ here and get the right answer.

#### Explanation:

The mole is just another number, admittedly it is a very large number, ${N}_{A} = 6.022 \times {10}^{23} \cdot m o {l}^{-} 1$. Let's do the problem by using $\text{dozens}$: $\text{1 dozen"="12 items of stuff}$.

$a .$ $\text{6 dozen S atoms}$ $\equiv$ $\text{72 sulfur atoms}$

$b .$ $\text{2 dozen}$ ${S}_{8}$ $\text{atoms}$ $\equiv$ $\text{192 sulfur atoms}$

$c .$ $\text{5 dozen}$ $S {O}_{2}$ $\text{molecules}$ $\equiv$ $\text{60 sulfur atoms}$ and $\text{120 oxygen atoms}$.

$d .$ $\text{2 dozen}$ $C {O}_{2}$ $\text{molecules}$ $\equiv$ $\text{24 carbon atoms}$ and $\text{48 oxygen atoms}$.

And the answer is clearly $b .$ Are you following me?
