$($a$)$ A waste contains $240$ mg$/$L of C$($H$2$O$)$ and $56$ mg$/$L of NH$3-$N$.$ Calculate the

carbonaceous ThOD, the nitrogenous ThOD, and the total ThOD of the waste

$($assuming that all the organic matter is biodegradable$)$

$($b$)$ A water sample has a concentration of $270$ mg$/$L of the readily degradable

compound glucose C$6$H$12$O$6.$ What would be the $($i$)$ COD and $($ii$)$ TOC be in

mg$/$L of this same sample?
