During the discharge of a lead storage battery, density of `H_(2)SO_(4)` fall from 1.3 to `1.14g//mL` Sulphuric acid of density `1.3g//ml` is 40W % and that of `1.14g//mL` is 20W% The battery holds two litre of the acid and volume remains practically constant during dicharging. The number of ampere- sec used from the battery is.

A

`3 xx 96,500`

B

`6 xx 96,500`

C

`9 xx 96,500`

D

`12 xx 96,500`

Text Solution

Verified by Experts

The correct Answer is:
B
`M_(1)- M_(2) = 10/98 [1.3 xx 40 - 1.14 xx 20]`
= 3 mole / litre = 6 moles Per 2 litres.
