What is the mpg of hydrogen?
The fuel efficiency of hydrogen vehicles is typically measured in miles per kilogram (mpgge - miles per gallon gasoline equivalent) instead of miles per gallon (mpg). On average, a hydrogen fuel cell vehicle can achieve around 60-70 mpgge, depending on the efficiency of the specific vehicle and driving conditions.

How much hydrogen is in one gallon of water?
If you mean hydrogen gas, H2, just naturally present in the water, then essentially none.If you mean how much hydrogen gas could be generated by the electrolysis of 1 gallon of water, that is a stoichiometry problem. The balanced reaction is:2H2O --> 2H2 + O2The mass of 1 gallon of water is 3.7854 kilograms, which is 210.3 moles of H2O. From the stoichiometry, there is a 1 to 1 (2 to 2) ratio of water to hydrogen produced, and so 210.3 moles of H2 will be produced. 210.3 moles of H2 weighs 420.6 grams, or just under one pound (see the Related Questions links to find out how to calculate the volume of that much H2 produced).If you mean hydrogen ions, H+, then it depends on the pH of the water. In perfectly pure, neutral water with pH of 7, then the concentration of H+ is 10-7 moles per liter. In one gallon, there are 3.7854 liters. So in one gallon of pure water, there are 3.7854 * 10-7 moles of H+.See the Related Questions for more information about pH and how it measures the concentration of H+.
