due to
1) You are in charge of a remediation strategy that requires aerobic, microbial respiration to degrade the compound ethanol in groundwater. There is 840mg/L ethanol in the groundwater; how much oxygen (total, steady state concentration in mg/L) will you need to completely oxidize the ethanol to CO2? Can you accomplish this using only atmospheric oxygen (21 % v/v) at 1 atm total pressure (Pro) and 25°C? If you cannot, what options do you have for increasing oxygen content...
