Aerosol cans are a convenient and economical way to dispense many products. They come in different shapes, sizes, and weights because there are so many items that need aerosols as their primary or secondary packaging. One very common type of aerosol is the spray can.
The most popular size is the 250 ml can which contains 2.3 g (or 2.30 g) of propane gas as a propellant; this means it’s mostly air with some other gases mixed in for good measure!
The gas in the spray can is what you use to propel a product out of the container.
One example would be whipped cream that comes right from an aerosol can.
Other popular usages for these cans are insecticides, hair sprays or deodorants because they have so much propellant and therefore shoot far distances making it easier to cover your target area.
Propane (C) has three hydrogen atoms, eight carbon atoms, and two oxygen atoms on its molecular formula which makes up propane gas with a total mass of 46 grams per mole. Propene (CH=CH-C,) also known as ethylene), has one more carbon atom than propane; this means there’s only two hydrogen molecules instead of three.
