Bacterial cells have been represented by the chemical formula C3H;NO,.Compute the theoretical oxygen demand of 30 mg/L of bacterial cells,assuming the following reactions apply: \mathrm{C}_{5} \mathrm{H}_{7} \mathrm{NO}_{2}+5 \mathrm{O}_{2} \rightleftharpoons 5

\mathrm{CO}_{2}+2 \mathrm{H}_{2} \mathrm{O}+\mathrm{NH}_{3} \mathrm{NH}_{3}+2 \mathrm{O}_{2} \rightleftharpoons \mathrm{NO}_{3}+\mathrm{H}^{+}+\mathrm{H}_{2} \mathrm{O}
