One molecule is composed of three atoms Sodium atom (Na), Oxygen atom (O), and Hydrogen atom (H).
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms

By definition, atoms are elements that are in their original (neutral) forms with the number of protons in the neucleus equals to the number of electrons in the shells. In Sodium Hydroxide (NaOH), the Sodium is Na+, which is an ion. Hydroxide in it's own is an ion (OH-). Oxygen receives electron from Sodium to form (OH-) and (Na+). In this case, Hydrogen is theoretically the only atom.

3.5 grams Na (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 9.2 X 1022 atoms of sodium ===================
1, because Na does not have a number after it.
