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.
