How many moles are there in 8.46 x 1024 molecules of sodium fluoride?

14.05moles

Explanation:

Given parameters:

Number of atoms of NaF  = 8.46 x 10²⁴atoms

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

             6.02 x 10²³ atoms makes up 1 mole of an atom

             8.46 x 10²⁴ atoms will contain =  = 14.05moles
