Find the time requried to liberate 1.0 litre of hydrogen at STP in an electrolytic cell by a current of `5.0 A`.

Explanation

Equivlent volume of `H_2 = 11.2 "litre"`
Number of equivalents of `H_(2) = 1/11.2`
`1` equivalent `-= 1F` charge
`1/11.2` equivalent `-= 1/11.2 F =Q`
`Q="it"`
`96500/11.2 = 5t implies t = 17235 ~= 29 min`.
