0.571 " mol."

Explanation:

First you need to find the conversion factor. We know that 1 mol. contains Avogadro's number of atoms and therefore our conversion factor will be:

\ 1 " mol." = 6.02xx10^23 " atoms"

3.44xx10^23 \ "atoms" xx (1 \ "mol.")/(6.02xx10^23 \ "atoms")

3.44xx10^23\ cancel("atoms") xx (1 \ "mol.")/(6.02xx10^23 \ cancel("atoms"))

0.571 " mol."
