the molar mass of 1 molecule of water = 1 H + 1 H + 16 O = 18 gmol-1
mass of 1 litre of water = 1 kg
Michael Farraday has shown that 1 liter of HHO can be produced
in 1 hour using 2.34 watts or 2.34 watt hours.
Michael Faraday was an exceptional and highly respected
researcher who investigated the electric current needed to convert
water into hydrogen gas and oxygen gas by electrolysis. His results
are accepted by pretty much every scientist everywhere. While he
expressed the results of his work in terms which would be meaningless
to the average person, his result is that an electrical input of
2.34 watts produces one litre of hydroxy gas in one hour.
and you are correct
The enthalpy of combustion for hydrogen is 286 kJ/mol
but 2.34 watts delivered over a 1 hour time period is only 8424 J
it would take 1800 hours to convert 1 liter of water into HHO
using 2.34 watts
but durring the 1 hour we can convert 1/1800 liters of water
into HHO using 8424 J
1 kg / 1800 = .000555 grams of water
--------------------------------------------------------
now for the energy we can get back
The molar mass of water is 18.01528 gmol-1
Avogadro's constant is 6.0221415 × 1023
So the mass of one molecule is
18.01528 gmol-1 ÷ 6.0221415 × 1023 = 2.991507 × 10-23g
Which is 2.991507 × 10-26kg
or: 0.00000000000000000000000002991507kg
so we determine the number of water molecules we have converted
into HHO durring the 1 hour by dividing the mass of 1 molecule
of water by the mass that was converted in the 1 hour.
.000555 kg of water / 0.00000000000000000000000002991507 kg 1 molecule of water =
= 18552565602540531505933.4781882 water molecules
by multiplying the number of water molecules by the 286 kJ/mol
we get 5306033762326592010696974761.8252 J
we used 8424 J we got back 5306033762326592010696974761.8252 J
now that was me using your 286 kJ/mol and Farradays 2.34 watt hours per liter HHO
how bout that !!!
thats probably why they use hydrogen and oxygen to launch the space shuttle
instead of gasoline.
