Composition of a mixture of gases

- Dec 20, 2017 -

The nature of the mixed gas depends on the type and composition of the constituent gases. The composition of the mixed gas has 3 kinds of representations.

① Volumetric Composition: The ratio of the total volume of the constituent gas to the gas mixture, expressed by RI

The so-called division volume refers to the composition of the gas in the mixture of gas temperature and total pressure alone occupied volume.

② Mass Composition: The ratio of the mass of the constituent gas to the total mass of the mixed gas, expressed by WI

③ Mole: Mole is the unit of mass of matter. If a system contains basic units (which can be atoms, molecules, ions, electrons or other particles) equal to the number of 0.012 kilograms of carbon -12 atoms, the amount of material in the system is 1 mol. The ratio of the molar number of the constituent gas to the total molar number of the mixed gas, expressed in XI
