The empirical formula for biomass of an unknown organism is CH
1.8O0.5N0.2. To grow this
organism, ethanol (C2H5OH) and ammonia are used as carbon and nitrogen sources, respectively.
Assume no product formation other than biomass. To produce 1 mole of biomass from 1 mole of
ethanol, the number of moles of oxygen required will be _______________.
Official Answer Key:
1.8
