The equation for aerobic production of acetic acid from ethanol is ____________

C2H5OH(ethanol) + O2(acetic acid) → CH3CO2H + H2O

Acetobacter aceti bacteria are added to vigorously-aerated medium containing 10 g l^-1 ethanol. After some time, the ethanol concentration is 2 g l^-1 and 7.5 g l^-1 acetic acid is produced. Calculate the Observed yield.
