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.

He then washes, dries, and weighs the precipitate. He finds he has collected 7.6 mg of silver chloride. Calculate the concentration of tin(II) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits.

Question
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 250. mL sample of groundwater known to be contaminated with tin(II) chloride, which would react with silver
nitrate solution like this:
SnCl,(aq) + 2 AgNO,(aq) → 2 AgCl(s) + Sn(NO
3),(aq)
The chemist adds 24.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the
precipitate. He finds he has collected 7.6 mg of silver chloride.
Calculate the concentration of tin(II) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of
significant digits.
