Answer:
This question requires use of Avogrado’s constant that states there are 6.02 x10^23 constituent particles contained in the amount of a substance given by one mole. Constituent particles are usually molecules, ions or atoms. Therefore there are 18.06x10^23 total atoms, 12.04x10^23 oxygen atoms, 6.02x10^23 carbon atoms and 6.02x10^23 carbon dioxide molecules.
