Chemical energy, electrical energy, and heat energy
Answer:
3.6132 * 10^24 atoms/molecules of 02
Explanation:
When we look at the balanced chemical equation, we can see that there are 6 moles of O2.
In order to convert from moles to formula units (atoms and molecules),
you need to multiply by avogadro's number.
6 moles *
/1 mol = 3.6132 * 10^24 atoms/molecules of 02
