The empirical formula for biomass of an unknown organism is CH_1.8O_0.5N_0.2. 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 mol of biomass from 1 mol of ethanol, the number of moles of oxygen required will be
