A 500 gallon propane tank weighs 946 lbs when empty and the 500 gallon propane tank weighs 2,650 lbs when full.

The heaviest liquid per gallon is liquid osmium which weighs as much as 176.7 lbs per gallon.

A 1000 gallon fuel tank weighs around 1,300 lbs to 1,400 lbs empty depending on the material it's made up.

Aluminum fuel tanks will weigh a bit less than steel or stainless steel fuel tanks.

Diesel weighs 7.1 lbs per gallon so 300 gallons of diesel weighs 2,100 lbs.

300 gallons of gasoline weighs 1,800 lbs as gasoline weighs 6 lbs per gallon.

5 gallons of gasoline weighs 30 lbs as 1 gallon of gasoline weighs 6 lbs.

1 gallon of gasoline weighs 6 lbs while a gallon of water weighs 8.34 lbs.

Water is around 25 percent heavier than gasoline which is 25 percent lighter than water of the same volume and gallons.

A gallon of water weighs 25 percent more than a gallon of gasoline.

Water weighs around 8.34 lbs per gallon.

A gallon of gasoline weighs 6 lbs even though they are both liquids.

The reason for water weighing more than gasoline is water is denser than gasoline.

The water is denser than gasoline so there essentially more molecules of water in a given volume.

For example in a given volume, there may be 15,000 molecules of gasoline but 20,000 molecules of water.

Water is also heavier than diesel which is why water settles at the bottom of a diesel tank and even a gasoline tank.

Diesel fuel is much denser than gasoline.

This means that there is more mass in the same volume.

Because diesel fuel is about 14 percent heavier, there is approximately 14 percent more energy in a gallon of diesel fuel vs. a gallon of regular gasoline.
