When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(11) sulfate (PbSO4) is reduced to lead at the cathode and oxidized to solid lead(II) oxide (PbO) at the anode. Suppose a current of 37.0 A is fed into a car battery for 20.0 seconds. Calculate the mass of lead deposited on the cathode of the battery. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.
