Q 1281301227.     During recharging of a lead storage battery, the density of sulphuric acid increased from `1.140` `gmL^(-1)` to `1.284` `gmL^(-1)`. Before recharging, sulphuric acid solution was `20%` by mass and after recharging the acid solution was `38%` by mass. The battery holds `3.0` `L` of the acid solution and the volume practically remained constant during recharge. Calculate How long (hours) would it take to charge the battery with a current of `5A` with `96.5%` efficiency?


A

`4.420` hrs

B

`44.20` hrs

C
