O2 has 2 atoms of oxygen.
There are 4 oxygen atoms on the reactant side of the equation 2SO2 + O2.
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
There are a total of 8 atoms in the chemical equation 4Na + O2 → 2Na2O. This can be calculated by adding up the number of atoms on both sides of the equation: 4 sodium atoms from 4Na, 2 oxygen atoms from O2, and 2 oxygen atoms from 2Na2O. Thus, the total number of atoms is 4 + 2 + 2 = 8 atoms.
In the balanced chemical equation 4 Cr(s) + 3 O2(g) → 2 Cr2O3(g), there are a total of 6 chromium atoms (2 from Cr and 4 from Cr2O3) and 6 oxygen atoms (6 from O2 and 3 from Cr2O3) on the right side of the equation.
There are 3 atoms in an oxygen molecule (O2).
There are 4 oxygen atoms on the reactant side of the equation 2SO2 + O2.

In the reaction 2SO2 + O2 → 2SO3, there are 4 atoms of sulfur (S) present on the left side and 4 atoms of sulfur on the right side. There are 6 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side.
In the balanced chemical equation 4 Cr(s) + 3 O2(g) → 2 Cr2O3(g), there are a total of 6 chromium atoms (2 from Cr and 4 from Cr2O3) and 6 oxygen atoms (6 from O2 and 3 from Cr2O3) on the right side of the equation.
There are 3 atoms in an oxygen molecule (O2).
There are two atoms of oxygen in an oxygen (O2) molecule.
12.54 (g O2) / 2*15.99 (g/mol O2) = 0.3921 mol O2 -->0.3921 (mol O2) * 6.022*1023 (molecules O2)/(molO2) == 2.361*1023 molecules O2= 4.723*1023 atoms O
in the oxygen that we breath there is 2 atoms (O2)
Most oxygen molecules are composed of two atoms of oxygen, and we frequently refer to oxygen as O2 (or O2) for this reason. Oxygen can also exist as the molecule called ozone, which is O3. Ozone is unstable, and will revert to O2 in a few minutes.
82.5 grams O2 (1 mole O2/32 grams)(6.022 X 10^23/1 mole O2) = 1.55 X 10^24 atoms of O2
ONE oxygen molecule (O2) contains two atoms of oxygen (O).
