To solve this question, we need to use the photosynthesis equation ratio:
For 1 mole of glucose produced, 6 moles of oxygen are produced.
Now we need to figure out how much oxygen a plant can produce. So:
1 mole of glucose --- 6 moles of oxygen
0.09 moles of glucose --- x moles of oxygen
x = 6 × 0.09
x = 0.54 moles of oxygen
Answer: The plant makes 0.54 moles of oxygen.
