Question

How much hydrogen, by volume or weight, is in a gallon of water? How much oxygen?

Answer 1

Way more then enough to run your car more efficiently than gasoline !

power boost

no emissions

free fuel

ocean water even works better

Answer 2

Water = H20  so

by mass

since the atomic mass number of H is 1.00794

and Oxygen has atomic mass number of 15.9994

the percent composition by mass of Hydrogen in

water is

1.00794*2/(1.00794*2+15.9994)

=2.01588/18.01528 =0.111898 as decimal

percent is 11.1898%

Now multiply that number by the weight of a gallon

of water and you have the amount of hydrogen by weight.  A gallon weighs 8 pounds so the hydrogen amount is 0.111898 *8 =0.895187 lb

which is 14.32 ounzes or 406.05grams

The oxygen would be the remainder of the 8 lb

which is 7.104813 lb =113.68 ounzes =3223 grams
