7,5276766125.1023 atoms.
The Avogadro number: 6,02214129(27)×1023.
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
1 molecule C6H12O6 = 6 atoms O, so : 36.00*1023 atoms O
Three: 1 C and 2 O atoms
Depending on the formula ! Two atoms in PbO2, three atoms in Al2O3, etc.
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

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
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
1.51x10^24 atoms of O
1 molecule C6H12O6 = 6 atoms O, so : 36.00*1023 atoms O
3 Fe atoms plus 4 O atoms totals 7 atoms.

16g of fat. 3g saturated fat.
There are 3 atoms in a molecule of water, 2 hydrogen (H) atoms and 1 oxygen atom (O). H2 O
3.15 x 6.02x1023 = 1.8963x1024 then multiply by two because there are 2 O atoms.1.8963x1024 x 2 = 3.7926x1024 O atoms
