One molecule is composed of three atoms Sodium atom (Na), Oxygen atom (O), and Hydrogen atom (H).
One molecule is composed of three atoms Sodium atom (Na), Oxygen atom (O), and Hydrogen atom (H).
6 Na means 6 atoms of Sodium 6 Na means 6 atoms of Sodium

1 mole Na = 6.022 x 1023 atoms Na 0.200 mole Na x (6.022 x 1023 atoms/1 mole Na) = 1.20 x 1023 atoms Na
6 atoms only
6.22 x 1023 atoms
1, because Na does not have a number after it.
7 atoms
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.
1 mole = 6.022 x 1023 4.8mol Na x (6.022 x 1023 atoms Na/mol Na) = 2.9 x 1024 atoms Na
