On electrolysis of water the net reaction occurred is represented by the following balanced equation
2H2O(l)→2H2(g)+O2(g)H2andO2
are are produced in 2:1 mol ratio.So the volumetric ratio under same conditions of temperature and prssure will also be 2:1.
Here total volume of electrolytic gas is 16.8L at NTP. So the volume of

gas produced is

at NTP.
The above equation suggests that 2mol or

gas is produced from 2moles or 36g water.
So 11.2L
