Answer:

1.12x10²³ atoms of F

Explanation:

A molecule is a group of 2 or 3 atoms that are bonded by electrostatic charges.

In 1 molecule of MgF2 there are 2 atoms of fluorine and 1 atom of magnesium.

Thus, there are 2 atoms of fluorine per molecule of MgF2. In 5.6x10²² molecules:

5.6x10²² molecules MgF2 * (2 atoms Fluorine / 1 molecule MgF2) =

1.12x10²³ atoms of F
