A 150 mL wastewater sample was analyzed for a total suspended solids concentration. The filter paper with dried solids was then placed in a 500 C furnace for 30 minutes and cooled in a desiccator. The weight of the filter paper with solids after this step was 2.0266 g. The dry mass of the filter paper was 1.9760 and the dry mass of the filter with solids after placing it in a 105 C oven was 2.0461 g. Determine the non-volatile suspended solids concentration in mg/L for this sample.
