$6.022 \times {10}^{23}$ $\text{atoms Fe}$
We're asked to find the number of atoms of $\text{Fe}$ in one mole of $\text{Fe}$.
To do this, we can use Avogadro's number ($6.022 \times {10}^{23}$) to solve for the atoms of iron. In fact, one mole of any substance contains $6.022 \times {10}^{23}$ particles of that substance.
Since iron is not diatomic (in which case the number of atoms is $\textcolor{red}{2} \times 6.022 \times {10}^{23}$), one mole of iron contains color(blue)(6.022xx10^23 color(blue)("atoms Fe"#.
