The chemical reaction equation for conversion of ethanol (C₂H₆0) to acetic acid (C₂H₄0₂) is:

Acetic acid is produced from ethanol during growth of Acetobacter aceti, which has the composition CH_1.80_0.5N_0.2. Biomass yield from substrate is 0.14 g g^{- 1}; product yield from substrate is 0.92 g g^-1. Ammonia is used as nitrogen source. How much gmol of oxygen is demanded for acetic acid production?
