The answer is 1/12,044.10e23.
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
1 mole
In one molecule of H2O, there are 2 moles of hydrogen (H) and 1 mole of oxygen (O).
4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2
In one oxygen atom, there is 1 atom of oxygen. The term "atom" refers to a single, indivisible unit of an element.

moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
12.8 grams oxygen (1 mole O/16.0 grams) = 0.800 moles of oxygen
4 moles of oxygen atoms are present in 4 moles of H2O
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
Since there is only 1 oxygen atom in CH2O, there is the same amount of oxygen atoms as there are molecules of CH2O. So the answer is 18.1 mole. But if you burn it, you will form oxygen in its natural form, which is O2. So there will only be the half the amount of the oxygen. Then the answer would be 18.1 / 2 = 9.05 mole.
3.70 moles NaClO4 (4 moles O/1 mole NaClO4) = 14.8 moles oxygen
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
Since oxygen is diatomic it requires 2 moles of oxygen.
