1. analyze the problem
you are given the number of atoms of zinc and must find the equiva-
lent number of moles. if you compare 4.50 x 1024 atoms zn with
6.02 x 1023, the number of atoms in one mole, you can predict that
the answer should be less than 10 moles.
known
unknown
number of atoms = 4.50 x 1024 atoms zn mol zn = ? mol
1 mol zn = 6.02 x 1023 atoms zn
