Answer:

follow me=follow back but if you mark me as a brainliest.

Explanation:

A million CO2 molecules have one million carbon atoms and two million oxygen atoms. A mole of CO2 molecules (we usually just say “a mole of CO2”) has one mole of carbon atoms and two moles of oxygen atoms.

so in 30 g co2 there is 30 moles of carbon atoms and 60 moles of oxygen atoms.
