It is equal to the total mass of oxygen and glucose formed.
Option (c) is correct.
Explanation:
- During photosynthesis carbon dioxide combines with water to form glucose and oxygen.
- the overall equation of photosynthesis can be written as;
- 6CO2 + 6 H2O ----> C6H12O6 + 6O2
- In this reaction, the amount of carbon dioxide used is equal to the amount of oxygen formed.
- according to the law of conservation of energy neither a mass is created nor destroyed, it changes from one form to another.
