The empirical formula for biomass of an unknown organism is CH1.8O0.5N0.2. 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

From 1 moles of biomass the total moles of Oxygen => 1 x (0.5 + 2) => 2.5 moles
From 1 mole ethanol = > Moles of O atoms => 1 moles.
Total moles = 2.5 – 1 = 1.5 moles.
