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 battery
b.) How long in hours will it take to recharge the battery back to the original sulfuric acid concentration using a currtent of 22.4A?
Assume you have a solution containing two volatile liquids. Given the data for liquid A: MM = 56.89 g/mole, partial pressure = 0.903 atm and for liquid B: MM = 14.52 g/mole, partial pressure = 0.995 atm
