Divide each number by ${N}_{A}$ and add them up.
1 mole of any substance contains 6.02 × 10^(23)# atoms (or molecules). This number is called the Avagadro Constant, ${N}_{A}$.
So to solve this problem we need to divide the numbers of atoms by ${N}_{A}$ to work out the number of moles of each substance and sum those to find the total number of moles of everything.
