The balanced chemical equation is:
2H2 + O2 ---> 2H2O
We are given the amount of the product produced from the reaction. This will be the starting point for the calculations.
355 g H2O ( 1 mol H2O/ 18.02 g H2O) ( 1 mol O2 / 2 mol H2O ) ( 32 g O2 / 1 mol O2 ) = 315.205 g O2
The chloroplasts convert radiant energy into chemical energy. Mitochondria convert food into energy.
Mitochondria = Animal Cell ONLY
Chloroplasts = Plant Cell ONLY
Hope this helps you! :)
