Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
8,23.1023 atoms Mg is equivalent to 1,366 moles.
This is equivalent to 1,4 moles.
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles

In 4 moles of magnesium hydroxide, Mg(OH)₂, there are a total of 20 atoms. Each formula unit of Mg(OH)₂ contains 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms, totaling 5 atoms per unit. Therefore, for 4 moles, you calculate 4 moles × 5 atoms/mole = 20 atoms.
8,23.1023 atoms Mg is equivalent to 1,366 moles.
This is equivalent to 1,4 moles.

The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
1 mole of any element contain 6,022 140 857.1023 atoms (Avogadro number).2,5 moles of magnesium contain 15,0553521425.1023.
how many moles are represented by 1.51 x 10^24 atoms Pb
5.1 moles Mg (6.022 X 1023/1 mole Mg) = 3.1 X 1024 atoms of magnesium ========================
There are 7.05 moles of oxygen atoms in 2.35 moles of sodium phosphate, as there are 3 oxygen atoms in each formula unit of sodium phosphate (Na3PO4).
