Acetobacter 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?
