C6H6O2
This is hydroquinone, one of several types, but I will use this one as example.
0.20 moles C6H6O2 (2 mole O/1 mole C6H6O2)(6.022 X 1023/1 mole O)
= 2.4 X 1023 atoms of oxygen
=====================
There are two atoms of oxygen in an oxygen (O2) molecule.
There are 2 oxygen atoms in 1 molecule of oxygen.
It depends on how many hydrogens are there and how many oxygen atoms there are.
There are four oxygen atoms in one molecule of H3PO4.
There are 2 oxygen atoms in dioxide
There are 3 atoms in an oxygen molecule (O2).
There are 2 atoms and 3 molecules in oxygen.
Heptane has 22 oxygen atoms.
3
The oxide Fe2O3 has 3 oxygen atoms in the molecule.
ONE oxygen molecule (O2) contains two atoms of oxygen (O).
It has 4 oxygen atoms.
