My teacher said this is a very hard question, but I'm trying to make an attempts. Can you guide me?

Question

A biologist places a plant in a closed chamber. A sensor in the chamber maintains the carbon dioxide level at the normal atmospheric concentration of 0.03%. Another sensor allows the biologist to measure the amount of oxygen produced by the plant over time. If the plant produces 0.001 mole of oxygen in an hour, how much Carbon dioxide had to be added to the chamber during that hour to maintain the atmospheric concentration of 0.03%?

Answer 1

look at the balanced chemical reaction...

6CO2+ 6H2O >>6 O2 + C6H12O6
So for each mole of oxygen produced, one mole of carbon dioxide was used.

Answer 2

Thanks, but I'm still really confused (that seems to be my mantra lately). I haven't had chemistry for 2 years and I'm at a loss, where to next?

Answer 3

Help! I'm not sure where you got that equation from.
