Answer:
If you meant moles then 3.13144 x 10^24
5.2 mol times 6.022 x 10^23 atoms / mol
Explanation:
Answer is: ammonia experience only dispersion intermolecular forces with BF₃ (boron trifluoride) because BF₃ is only nonpolar molecule (vectors of dipole moments cansel each other, dipole moment is zero).
The London dispersion force (intermolecular force) <span>is a temporary attractive </span>force between molecules.
<span>Made up of particles packed relatively close together, having an indefinite shape but a definite volume</span>
