4). A 100-mL water sample is collected from the activated sludge process of municipal wastewater treatment. The sample is placed in a drying dish (weight = 0.5000 g before the sample is added) and then placed in an oven at 104°C until all moisture is evaporated. The dried weight is 0.5625 g. A similar 100 mL sample is filtered and the 100 mL liquid sample that passes through the filter is collected and placed in another drying dish (weight = 0.5000 g before the sample is added). This sample is dried at 104°C, and the dried dish's weight is recorded as 0.5325 g. Determine the concentration (in mg/L) of (a) total solids, (b) total suspended solids, and (c) total dissolved solids.
