3. The mass of mercury flowing out of a dripping electrode in 100 s is 0.196 g. The lifetime of 10 drops of mercury is 43.2 s. When working with this electrode for a 1.00*10-3 M PB2 solution, a current of 8.76 μA was observed. For a lead solution of unknown concentration, a current of 16.31 μA was observed for a new capillary with a dripping period of 6.13 s and a mercury flow rate of 3.85 mg/s. Calculate the unknown lead concentration.
