the concentration of sulfuric acid in the lead-storage battery of an automobile over a period of time has decreased from 38.0 percent by mass(density =1.29g/mL) to 26.0 percent by mass(1.19g/mL). assume the volume of the acid remains constant at 724 mL.a.) Calculate the total charge in coulombs supplied by the batteryb.)How long in hours will it take to recharge the battery back to the original sulfuric acid concentration using a currtent of 22.6A?
