because propane is a gas and at different temperatures or pressures it's density varies a lot in the same size container. Once pressurized, it will liquify. So to measure it fairly, it is measured by wieght.

What does a full 5 gal propane tank weigh?

Depends on the mass and what you are weighing. Gallons is a measure of 'capacity'. In a five gallon container you could put five gallons of water, which would weigh about 50lbs, but five gallons of petrol, which is lighter than water, would weigh less.


What chemical is present in LPG?

Varieties of LPG bought and sold include mixes that are primarily propane (C3H8), primarily butane (C4H10) and, most commonly, mixes including both propane and butane, depending on the season - in winter more propane, in summer more butane. So that people can smell the gas (for safety) chemicals that smell are added - ethanethiol, thiophene and amyl mercaptan.


Who uses propane?

well, for example in the famous animated comedy "King of the Hill' Hank sells propane supposedly beause its better for the environment but seriously now it's used for many other stuff such as: Other * Propane is used as a feedstock for the production of base petrochemicals in steam cracking. * Propane is used in some flamethrowers, as the fuel, or as the pressurizing gas. * Some propane becomes a feedstock for propyl alcohol, a common solvent. * Propane is the primary fuel for hot air balloons. * It is used in semiconductor manufacture to deposit silicon carbide. * Propane is mixed with silicone to form a propellant (sold as green gas) which is used to power gas guns used in airsoft combat gaming. * Liquid propane is commonly used in theme parks and in the movie industry as an inexpensive, high-energy fuel for explosions and other special effects.


What is difference between propane and commercial propane?

The difference is the bonds between the first pair of carbons. A Carbon atom requires 4 bonds in a molecule. In Propane, the three carbons have 1 bond between each of them, and the rest of their bonds are used for hydrogen, resulting in a C3H8 molecule. In Propene, the first 2 carbons will have a double bond, resulting in 2 less hydrogens in the molecule, C3H6. The difference between alkanes and alkenes are that a double bond is shared between a pair of the carbon atoms. In pro-2-ene, this would be the 2nd and 3rd carbon sharing a double bond. In just propene, it's the 1st and 2nd.


Constituents of LPG?

Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season---in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN 589
