About $2.5 \text{ moles}$

#### Explanation:

$\text{Number of moles}$ $=$ $\text{Mass"/"Molar mass}$

$=$ $\frac{80 \cdot g}{32.06 \cdot g \cdot m o {l}^{-} 1}$ $=$ ??mol

Note that sulfur likely exists in its elemental state as ${S}_{8}$. I am perfectly justified in treating sulfur as $S$. The number of $\text{sulfur atoms}$ is the same in each case.
