1. Moles to Molecules:

* One mole of any substance contains 6.022 x 10²³ particles (Avogadro's number).

* Since F₂ represents a molecule of fluorine, 3.6 moles of F₂ contain:

3.6 moles F₂ * (6.022 x 10²³ molecules F₂ / 1 mole F₂) = 2.168 x 10²⁴ molecules F₂

2. Molecules to Atoms:

* Each molecule of F₂ contains two fluorine atoms.

* Therefore, the total number of fluorine atoms is:

2.168 x 10²⁴ molecules F₂ * (2 atoms F / 1 molecule F₂) = 4.336 x 10²⁴ atoms F

So, there are 4.336 x 10²⁴ atoms of fluorine in 3.6 moles of F₂.
