In a fermentation process, each mole of glucose is converted to biomass
(CH1.8O0.5N0.2), with a biomass yield coefficient of 0.4 C-mol/C-mol, according
to the unbalanced equation given below.
C6H12O6 + NH3 + O2 → CH1.8O0.5N0.2 + CO2 + H2O
The moles of oxygen consumption per mole of glucose consumed during
fermentation is _________.
