Answer:

#6.022xx10^23# #"atoms Fe"#

Explanation:

We're asked to find the number of atoms of #"Fe"# in one mole of #"Fe"#.

To do this, we can use Avogadro's number (#6.022xx10^23#) to solve for the atoms of iron. In fact, one mole of any substance contains #6.022xx10^23# particles of that substance.

Since iron is not diatomic (in which case the number of atoms is #color(red)(2) xx 6.022xx10^23#), one mole of iron contains #color(blue)(6.022xx10^23# #color(blue)("atoms Fe"#.
