Molar volume of gas visualized
The molar volume [22.4L at STP] plays a vital role in stoichiometric calculations because it is the link between volume and mass in reactions involving gases.A mole is a basic unit of the amount or quantity of a substance. It may be atoms, molecules, ions or group of ions.
