When electric current is passed through acidified water, 1 12 mL of hydrogen gas at STP collected at the cathode in 965 seconds. The current passed in amperes is

Answer»

`1.0`
`0.5`
`0.1`
`2.0`

SOLUTION :112 mL of `H_(2)` at `STP =(2XX 112G)/(22400)`
(Since 22400 mL at STP =M.wt)
Amount deposiled `=(Eq. wt xxi XXT)/(96500)`
`therefore (2xx 112)/(22400) =(1xx965xxi)/(96500)`
`i=1` AMP
