One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.

Suppose an EPA chemist tests a 250mL sample of groundwater known to be contaminated with cadmium chloride, which would react with silver nitrate solution like this:

CdCl2 (aq) 2AgNO3 (aq) = 2AgCl (s) Cd(NO3)2 (aq)

The chemist adds 82mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 6.2mg of silver chloride.

Calculate the concentration of cadmium chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits.
