Assume that a waste contains 395.0 mg/L of biodegradable CH2O and is processed through a 190000.0 L/day sewage treatment plant which converts 40% of the waste to CO2 and H2O. Calculate the volume(L) of air (at 25 degrees, 1 atm) required for this conversion. Assume that the O2 is transferred to the water with 20% efficiency.

Hint: Calculate mass of carbohydrate processed, use chemical equations to calculate mol oxygen needed to oxidize the carbohydrate, and the volume of air needed.
