Answer:Number of atoms =1.806×10²⁴

Explanation:You have the number of moles of Carbon tetrachloride which is n=3

And you are looking for number of atoms that are in the sample, which are represented by the letter “N”

The formula that has both number of moles(n) and number of atoms(N) is written as n=N/Na

Na is called the Avogadros number and it is equal to 6.08×10²³, it never changes(it is a constant)

So you will substitute the number of moles and the avogadros number to you formula, and the only unknown will be the number of atoms which you are looking for

NB: N does not represent the number of atoms only. It may also represent the number of particles or molecules…
