A. aceti converts alcohol to acetic acid according to the stoichiometric relation

C2H5OH + O2 🡪CH3COOH + H2O

In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism produces 16 g/l acetic acid and 2 g/l was the residual ethanol concentration. What are the theoretical and observed yields of acetic acid expressed in g/g ethanol?
