As would be more apparent from its properly written formula, Zn(ClO3)2, each formula unit contains 6 oxygen atoms, the product of the subscript immediately following the oxygen atomic symbol and the subscript following the parenthetical formula of the chlorate polyatomic ion of which the oxygen atoms present are a part.
I'm really not sure what chemical formula this is, if you're looking for Zinc chloride, there is no oxygen, and the chemical formula is ZnCl2 (2 being a subscript). In this particular chemical formula, if the 3 is a subscript, then there would be 6 oxygen (O) atoms in there, I believe. If the 3 is not a subscript, there would still be 6 oxygen atoms.

1 molecule C6H12O6 = 6 atoms O, so : 36.00*1023 atoms O
7,5276766125.1023 atoms.
Three: 1 C and 2 O atoms
Depending on the formula ! Two atoms in PbO2, three atoms in Al2O3, etc.
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
Zinc Chlorine dioxide
1.51x10^24 atoms of O
1 molecule C6H12O6 = 6 atoms O, so : 36.00*1023 atoms O
7,5276766125.1023 atoms.
3 Fe atoms plus 4 O atoms totals 7 atoms.

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
There are 3 atoms in a molecule of water, 2 hydrogen (H) atoms and 1 oxygen atom (O). H2 O
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
ONE oxygen molecule (O2) contains two atoms of oxygen (O).

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
