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.
That is assuming that they haven't reacted to form molecules, which I think based on the question is a fair assumption.

I will leave my answer there allowing you to go ahead and solve the problem using that method. But if you want a full numerical answer leave a comment.
