* Carbon Dioxide Formula: The chemical formula for carbon dioxide is CO₂. This means each molecule has 1 carbon atom and 2 oxygen atoms.

* Two Molecules: You're asking about *two* molecules of carbon dioxide (2CO₂).

Therefore, in 2 molecules of carbon dioxide:

* Carbon Atoms: 2 molecules * 1 carbon atom/molecule = 2 carbon atoms

* Oxygen Atoms: 2 molecules * 2 oxygen atoms/molecule = 4 oxygen atoms
