TO HELP W/ THE DEBATE ON HYDROGEN/OXYGEN PRODUCTION DURING ELECTROLYSIS:


This is what my Thermodynamics Book says (Fundementals of Engineering Thermodynamics):

There are 2.016 kg/kmol of H2

32.00 kg/kmol of O2

Wikipedia - Hydrogen @ 0 degrees Celcius (32 degrees F) & 1 atm

H2 - 0.08988 g/L or 0.00008988 kg/L

Wikipedia - Oxygen @ 0 degrees Celcius (32 degrees F) & 1 atm

O2 - 1.429 g/L or 0.001428 kg/L


or

H2 - 11126 L/kg

O2 - 700 L/kg


Since there are 2kmol of H2 per kmol of O2:

4.032 kg H2

32.00 kg O2

in 36.032 kg H2O

Multiplying through:

44860 L of H2

22400 L of O2

Determining the ratio:

44860/(44860+22400) = .667 = 66.7% Hydrogen

100% - 66.7% = 33.3% Oxygen


TO CONCLUDE: There should be 2x as much gaseous Hydrogen after electrolysis than Oxygen.

If my math is faulted please correct me.
