Converting between Moles to Molecules to Atoms

In this conversion, A mole of any substance is 6.02×1023 molecules of that substance.

To convert moles to atoms, you first convert the mole to molecules then use the element's subscripts and multiply it to the answer.
0.001 moles water × ( 6.02×1023 water molecules
1 mole water
) = 6.02×1020 water molecules
100 water molecules × ( 1 mole water
6.02×1023 water molecules
) = 1.66× 10-22 moles water
