In a lead strage battery, Pb(anode) and ...

In a lead strage battery, Pb(anode) and `PbO_(2)` (cathode) are used. Concentrated `H_(2)SO_(4)` is used as electrolyte. The battery holds 3.5 llitre acid with it. In the discharge process, the density of acid fell from 1.294 to 1.139 g/mL. The sulphuric acid of dencity 1.294 g `mL^(-1)` is 39% by mass and that of density 1.139 g/mL is 20% by mass.
Number of ampere-hours for which the battery must been used is :

A

26504 amp-hrs

B

2650.4 amp-hrs

C

265.04 amp-hrs

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.294 g mL^(-1) to 1.139 g mL^(-) . Sulphuric acid of density 1.294 g mL^(-1) is 39% by weight and that of density 1.139 g mL^(-1) is 20% by weight. The battery hold 3.5 litre of acied and discharge. Calculate the no. of ampere hour for which the battery must have been used. The charging and discharging reactions are: Pb+SO_(4)^(2-) rarr PbSO_(4)+2e (charging) PbO_(2)+4H^(+)+SO_(4)^(2-)+2e rarr PbSO_(4)+2H_(2)O (discharging)
