4CuFeS2(s)+17O2(g)+10H2O(l)4Fe(OH)3(s)+4CuSO4(aq)+4H2SO4(aq) In a laboratory experiment to study weathering, a mining engineer put a 1.86kg sample of CuFeS9(s) near an empty 40L container. Simulated weathering experiments were conducted and the runoff was collected, leading to 35.3L of solution. A 25.00 mL aliquot of this solution was analyzed with 0.0100MNaOH(aq). The titration required 38.8mL of base. (a) Wffat was the concentration (in M ) of sulfuric acid? M (b) Assuming the only acid in the container comes from the reacted chalcopyrite, what mass (in g) of the chalcopyrite has reacted? g (c) What percentage of the chalcopyrite reacted in this experiment? %
