Acetobacter aceti converts alcohol to acetic acid according to the stoichiometric  relation 
 C2H5OH + O2   →       CH3COOH + H2
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?
