2.68 x 10^24 atoms of cu equal how many moles? !

- 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.
