LPG is a mixture of 

Liquefied petroleum gas is a mixture of ethane, propane and butane. 

It is a mixture of hydrocarbons that typically contain 3 to 4 carbon atoms. The main components of LPG include propane (C₃H₈), n-butane (C₄H₁₀), iso-butane, and a small amount of ethane (C₂H₆). These gases are liquefied under pressure for easy storage and transportation. LPG is widely used as fuel for cooking, heating, and in vehicles due to its high energy content and convenience.

LPG, or Liquefied Petroleum Gas, is a mixture of several hydrocarbons, primarily butane, propane, and sometimes ethane.

The main component in LPG is butane, which makes up a significant portion of the mixture. Propane is also commonly found in LPG, especially in colder climates, as it has a lower boiling point and works better at lower temperatures.

LPG is stored as a liquid under pressure in gas cylinders or tanks, making it easy to transport and use as fuel. When the pressure is released, the liquid turns into gas, which can be used for cooking, heating, and even in vehicles. Its versatility and easy storage make it a popular choice for many household and industrial applications.
