In photosynthesis carbon dioxide and water are combined to yield glucose and oxygen gas. I f 16.7 kg of water are adsorbed by a tree, what volume of oxygen would the tree yield

Answer 1

6CO₂(g) + 6H₂O ==> C₆H₁₂O₆ + 6O₂

16.7 kg H₂O x 1000g/kg x 1 mol/18 g = 928 mol H₂O

928 mol water x 6 mol O₂ / 6 mol water = 928 mol O₂

The volume of O₂ depends on the temperature and pressure. If the system is at STP, then 1 mol of gas = 22.4 liter.

Here we have 928 Mol x 22.4 L/ Mol = 20,787 L H₂O
