Deuterium oxide -- or "heavy water" -- is composed of water molecules formed by two deuterium atoms and one oxygen atom. Deuterium is a stable isotope of hydrogen containing one proton and one neutron in its nucleus. The more common hydrogen atom contains no neutrons in its nucleus. Heavy water is about 10 percent denser than regular water. Its specific gravity is 1.106. Since regular water weighs 8.34 pounds per gallon, a gallon of heavy water, therefore, weighs 9.22 pounds.
1 liter of liquid hydrogen weighs only 0.07 kg. That is a density of 70.8 kg/m³ (at 20 K)
There are 3.7854 liters per gallon, so 1 gallon of liquid H2 weighs 0.268 kg.
There are 2.2046 lbs per kilogram, so 1 gallon of liquid H2 weighs 0.5908 lbs.
Compare that with the weight of 1 gallon of water: 8.3454 lbs (more than 14 times heavier!)
1 gallon is 0.13368 cubic foot (rounded), regardless of what's in it, or even if it's empty.
The density of liquid oxygen is around 1141 kg/m^3 or around 9.50 lb/gal. So the answer would be 9.50 lb Found this info at http://en.wikipedia.org/wiki/Liquid_oxygen
Hydrazine is 8.4 lb/gallon
it weighs about 1.00 79 .

If it were a gallon of liquid hydrogen, you might get a couple miles but a gallon hydrogen gas is not enough to do much
11.630 lbs
depends on the density?
The mass is 4,178 kg (for the US gallon).
depends on the liquid. One gallon of gasoline would be very different from one gallon of mercury
2350lbs. on average
A gallon is a unit of measurement used for liquid, and is not applicable to solid substances, e.g rocks.
Can't buy hydrogen by the gallon
how much does a gallon of concrete weigh
1 gallon
Weight of Imperial Gallon of Water1 gallon [UK] = 1.201 gallon [US, liquid]One US gallon weighs 8.34 pounds, so an imperial gallon weighs about 16.6 percent more, or almost exactly 10 pounds.
A gallon of butter weighs about 21.5 pounds. A gallon of milk weighs about 8 pounds but it takes over 20 pounds of milk to make a gallon of butter.
