Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Answer:- 
atoms of Cu are equals to 4.45 moles.
Solution:- It is a atoms to moles unit conversion for which we divide the given number of atoms by Avogadro number.
We have been given with atoms and asked to convert them to moles.
The set up for this unit conversion problem would be as:
= 4.45 moles
So, there would be 4.45 moles of Cu in atoms of Cu.
