# How many moles of copper are equivalent to 3.44*10^23 atoms of copper?

Jul 3, 2016

$0.571 \text{ mol.}$

#### 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:

$\setminus 1 \text{ mol." = 6.02xx10^23 " atoms}$

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

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

$0.571 \text{ mol.}$
