Question
When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(II) sulfate PbSO4 is reduced to lead at the cathode and oxidized to solid lead(II) oxide PbO at the anode.
Suppose a current of 59.0A is fed into a car battery for
66.0 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
