"You have 2 mol/min of pure carbon fed to your system . Calculate the airflow rate (Liters/min), at STP (zero celcius, 1 atm) as atmospheric air required to oxidize all of this carbon to CO2. You can assume carbon is 12 g/mol and oxygen is 16 g/mol, and for simplicity that the air is 80% Oxygen and 20% Nitrogen."

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...
