Approx. 8 pounds.
Gasoline weighs about 6.2 lbs per gallon.
1 gal liquid H2 weighs approximately 0.25 kg which is 2.7 imes more powerful (energy content) than the gasoline at the same weight. So we are talking roughly 0.675 kg gasoline=1.45 lb=-.9 literl gasoline=0.23 gal gasoline 5 + miles (assuming 1 gal/20 miles)
8.66 lbs.
yes, by mixing new gas with it, 1 gal new to 1/2 gal old gas,
390 mi/15 gal = 26 mi/gal = 26 mpg
300L X 0.2642 Gal/L = 79.26 gal
It can vary somewhat, by season, colder seasons the weight will be slightly higher, because of density, but for most instances you can use 6.1 lbs./gallon
On average, one gallon of propane contains about 0.73 gallons of gasoline equivalent. This means that you would need around 1.37 gallons of propane to equate to 1 gallon of gasoline in terms of energy content.
(750 mi) x ( 1 gal / 12 mi) x (4.12 $/gal) = $257.50
