How much does a gallon of liquid hydrogen weigh?

Answer 1

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.

Answer 2

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!)

Answer 3

1 gallon is 0.13368 cubic foot (rounded), regardless of what's in it, or even if it's empty.

Answer 4

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
