Answer:
During the composition of water, Hydrogen and Oxygen combine in a ratio of 1:8 by mass and 2:1 by molar composition.
2H₂+O₂→2H₂O
Therefore, During Electrolysis, the gases obtained are in the same molar and mass ratio, due to "The Law of conservation of Mass".
Electrolysis:
2H₂O→(Electricity)→2H₂+O₂
The gases obtained are:
At Cathode, Hydrogen (double the volume of other gas)
At Anode, Oxygen (Half the volume of hydrogen gas)
