The Avogadro number: 6,02214129(27)×1023.
7,5276766125.1023 atoms.
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
4.1 X 10^-12g O (1mol O/16g O )(6.022 X 10^23/1mol O )(1mol atoms O/6.022 X 10^23 ) = 2.56 X 10^-13 moles of atoms

The Avogadro number: 6,02214129(27)×1023.
7,5276766125.1023 atoms.
The Avogadro number: 6,02214129(27)×1023.
1mol O = 16.0g (rounded to 1 decimal place) 1mol O atoms = 6.022 x 1023 atoms 16g O x 1mol/16g = 1mol O 1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
16 g O x 1 mol/16 g = 1 mole and 1 mole = 6.02x10^23 atoms of O8g S x 1 mol/32 g = 0..25 moles S and then 0..25 moles x 6.02x10^23 atoms/mole = 1.5x10^23 atoms of S, or rounding to 1 significant figure, you have 2x10^23 atoms of S
That is 3.2 teaspoons.
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
4.1 X 10^-12g O (1mol O/16g O )(6.022 X 10^23/1mol O )(1mol atoms O/6.022 X 10^23 ) = 2.56 X 10^-13 moles of atoms
There are more atoms of sulfur in 16 grams than there are atoms of iron in 56 grams.
