You would multiply moles of fluorine by Avogadro's number to get the units atoms of fluorine.

Here's why:

* Avogadro's number is a fundamental constant that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. Its value is approximately 6.022 x 10²³ particles per mole.

* Moles represent a unit of amount, like a "dozen" but for atoms or molecules.

Therefore, to convert from moles to atoms, you multiply by Avogadro's number:

Moles of Fluorine * Avogadro's Number = Atoms of Fluorine
