How many atoms of oxygen are present in the reactants
6CO2+6H2O=C6H12O6+6O2

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

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
