The concentration of lead ions (Pb2+) in a sample of polluted water that also contains nitrate ions (NO3−) is determined by adding solid sodium sulfate (Na2SO4) to exactly 500 mL of the water. Calculate the molar concentration of Pb2+ if 0.00350 g of Na2SO4 was needed for the complete precipitation of lead ions as PbSO4.
