Citric acid can be produced according to the above formula by aerobically growing Aspergillus niger mold in a solution containing glucose as a substrate. The chemical composition of this mold is CH1.8O0.6N0.12. The yield of biomass from glucose is 0.34 g g-1 and the yield of citric acid from glucose is 0.535 g g-1. Using a reduction balance, calculate how many moles of oxygen are needed per mole of glucose. In this calculation, use the following rounded even values as atomic weights for all calculations: C=12 g/mol, H=1 g/mol, O=16 g/mol ja N=14 g/mol. So how many moles of oxygen are needed per mole of glucose ? Calculate the answer to three decimal places.
C6H12O6 + a*O2 + b*NH3 --> c*CH1.8O0.6N0.12 + d*CO2 + e*H2O + f*C6H8O7
