A $50$ $\text{mL}$ sample of industrial wastewater is taken into a silica crucible. The empty weight of the crucible is $54.352$ $\text{g}$. The crucible with the sample is dried in a hot air oven at $104\;^{\circ}C$ till a constant weight of $55.129$ $\text{g}$. Thereafter, the crucible with the dried sample is fired at $600\;^{\circ}C$ for $\text{1 h}$ in a muffle furnace, and the weight of the crucible along with residue is determined as $54.783$ $\text{g}$. The concentration of total volatile solids is _____________________
- $\text{15540 mg/L}$
- $\text{8620 mg/L}$
- $\text{6920 mg/L}$
- $\text{1700 mg/L}$
