Problem

Bacterial digestion is an economical method of sewage treatment. The reaction

5 CO2 (g) + 55NH4+ (aq) + 76 O2 (g) —bacteria→

C5H7O2N (s) + 54 NO2- (aq) + 52 H2O (l) + 109 H+ (aq)

is an intermediate step in the conversion of the nitrogen in organic compounds into nitrate ions. What mass of C5H7O2N is produced in a treatment plant for every 1.0 x 104 kg of wastewater containing 3.0% NH4+ ions by mass? Assume that 95% of the ammonium ions are consumed by the bacteria.
