Dear student,
The equation of photosynthesis reaction is as follows.
6H2O + 6CO2 → C6H12O6 + 6O2
From the above equation, 6 mole of water produces 1 mole of glucose.
āā108g of water required to produce =180 g glucose
36 gram glucose is formed by =108 x 36 /180 =21.6 g water.
Hence, 21.6 g water will be required to produce 36g of glucose.
