Question #ac336

Answer 1

`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"`.
