Andrew dissolved 10.00 grams of an iron ore sample in 5.00 L of acid to produce a stock solution. Josh ran a trial of the analytical procedure on the stock solution, but found the solution was too concentrated to be used. So Josh prepared a 1:250 dilution of the sample solution, and, after running the analytical procedure successfully, found the solution contained 1.62 x 10-5 mol/L Fe2+ (aq). What is the mass of iron in the meteorite sample?
