A suspended solids analysis is run on a sample. The tare mass of the crucible and filter is 55.3520 g. A sample of 260 mL is then filtered and the residue dried to constant mass at 103 degrees C. The constant mass of the crucible, filter, and the residue is 55.3890 g. The residue is then decomposed at 600 degrees C to drive off the volatile matter. Assume that the filter does not decompose at this temperature. After decomposition, the constant weight of the crucible and the residue was again determined and was found to be equal to 30.3415 g. What is the percent volatile matter in the sample?
