Question

What mass of oxygen is produced if 22.7 mol of carbon dioxide is consumed in a controlled photosynthesis reaction?

Answer 1

Chemical equation →

6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O

For 6 mole of CO2 , 6 Mole of O2 is produced

So, for 22.7 mole of CO2 , 22.7 mole of O2 is produced

Thus , No. of moles of O2 = 22.7 mol.

Moler mass of O2 = 16 × 2 → 32g

Now, we know

No of moles = mass / molar mass

22.7 = mass/32

Mass = 726.4 g
