During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.294 to 1.139g // mL. Sulphuric acid of density 1.294 g // mL is 39% H_(2)SO_(4) by weight and that of density 1.139g // mL is 20% H_(2)SO_(4) by weight. The battery holds 3.5 L of the acid and the volume remained practically constant during the discharge. Calculate the number of ampere-hours for which the battery must have been used. The discharging reactions are Pb+ SO_(4)^(2-) rarr PbSO_(4) + 2e^(-) ( chargining) PbO_(2) + 4H^(+) + SO_(4)^(2-) + 2e^(-) rarr PbSO_(4) + 2H_(2) O ( dischargining)
