A sample of water is to be analyzed for solids content. Ten liters (10.0 L) of water are passed through a filter initially weighing 15.0 g. After drying at 105 oC, the filter plus residual weighs 43.0 g. The filter is heated to 550 oC, and the filter plus residual then weighs 37.0 g. Another 10.0 L sample of the same water is evaporated, without filtering, yielding a residual mass of 40.0 g. This residual is heated to 550 oC and the remaining mass is reduced to 25.0 g. What are the values for TS and TDS for this water?
