An elecric current 0.25 ampere was passed through acidified water for two hours, the volume of `H_(2)` produced at N.T.P is

A

20.16 litres

B

0.2016litres

C

2.016litres

D

0.4032 litres.

Text Solution

Verified by Experts

The correct Answer is:
B
`W=(E)/(96500)xxIxxt`
`=(1)/(96500)xx0.25xx2xx60=0.01865g`
`2gH_(2)` has volume =22.4 litre
`0.01865g` of `H_(2)` has volume
`=(22.4)/(2)xx0.01865=0.2016` litre.
