What is the exact chemical formula of natural gas?

Answer 1

LPG is not a pure compounds, so it doesn't really have one, but it's probably mostly propane (C3H8) and/or a mixture of isomers of butane (C4H10). By the time you reach pentane and higher alkanes, it's normally called pet (petroleum) ether rather than LPG.

Answer 2

The exact chemical formula of natural gas is typically a mixture of hydrocarbons, primarily methane (CH4), but can also contain small amounts of ethane (C2H6), propane (C3H8), butane (C4H10), and other gases.

Answer 3

CH4 - methane. The gas company adds the "gas" smell to it, methane is odorless normally.

Answer 4

Liquefied petroleum gas is not one single chemical but a mixture of several hydrocarbons which also include impurities. There is, therefore, no chemical formula.
