A chemistry student needs to analyze a water sample to determine the concentration of a certain contaminant. The student knows the initial concentration of the contaminant in the source water and the volume of the source water used to produce the final sample. Can the student use mass balance calculations to determine the concentration of the contaminant in the final water sample? If so, what is the concentration of the contaminant in the final sample?
