A chemistry student is asked to determine the concentration of a particular compound in a sample of drinking water. The student collects a 100 mL water sample and adds a known amount of a standard solution containing the compound. After allowing the solution to equilibrate, the student measures the concentration of the compound in the new solution using a spectrophotometer, to be 0.0125 M. Assuming mass balance, calculate the concentration of the compound in the original drinking water sample.
