A common car battery consists of six identical cells, each of which carries out the reaction: Pb PbO2 2HSO4- 2H --> 2PbSO4 2H2O * Suppose that in starting a car on a cold morning a current of 125 amperes is drawn for 21.0 seconds from a cell of the type described above. How many grams of Pb would be consumed
