$100$ mL of wastewater sample in a porcelain dish was dried in oven at $105\backslash$deg C after being

evaporated on water bath. The weight was determined as $61\mathrm{.}6032$ g$.$ The weight of the

same dish was found to be $61\mathrm{.}5910$ g after being ignited in the furnace at $550\backslash$pm $50\backslash$deg C$.$ If the

tare weight of the porcelain dish was $61\mathrm{.}3786$ g$,$ calculate TS$,$ VS and FS concentrations

in mg$/$L$.$
