Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
5,25 moles (in anhydrous sodium sulphate)
28.75 grams sodium (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 7.531 X 1023 atoms of sodium ------------------------------------------
72.6 grams of sodium (1 mole Na/22.99 grams)(6.022 X 10^23/1 mole Na) = 1.90 X 10^24 atoms of sodium
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
1 mole
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
5,25 moles (in anhydrous sodium sulphate)
28.75 grams sodium (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 7.531 X 1023 atoms of sodium ------------------------------------------
The formula unit of sodium, as with most other metals, is a single atom. Therefore, one mole of sodium contains Avogadro's Number of atoms, about 6.022 X 1023.

145 grams NaCl (1 mole NaCl/58.44 grams)(1 mole Na +/1 mole NaCl)(6.022 X 1023/1 mole Na +) = 1.49 X 1024 ions of sodium =====================
72.6 grams of sodium (1 mole Na/22.99 grams)(6.022 X 10^23/1 mole Na) = 1.90 X 10^24 atoms of sodium
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
16 grams? I would purpose that this has a little something to do with the law on conservation of mass. I could always be wrong though...
