Suppose an epa chemist tests a 200.ml sample of groundwater known to be contaminated with iron(ii) chloride, which would react with silver nitrate solution like this: fecl2 (aq) + 2agno3 (aq) → 2agcl (s) + feno32 (aq) the chemist adds 14.0m m silver nitrate solution to the sample until silver chloride stops forming. she then washes, dries, and weighs the precipitate. she finds she has collected 6.9mg of silver chloride. calculate the concentration of iron(ii) chloride contaminant in the original groundwater sample. be sure your answer has the correct number of significant digits.
