Composition of gas mixture
The nature of the gas mixture depends on the type and composition of the constituent gas. There are three ways to express the composition of the gas mixture.
①Volume component: the ratio of the partial volume of the constituent gas to the total volume of the mixed gas, expressed as ri
The so-called partial volume refers to the volume occupied solely by the constituent gas at the temperature and total pressure of the mixed gas.
②Mass composition: the ratio of the mass of the constituent gas to the total mass of the mixed gas, expressed by wi
③ Molar composition: Molar is the unit of quantity of substance. If the number of basic units (which can be atoms, molecules, ions, electrons, or other particles) contained in a system is equal to the number of 0.012 kilograms of carbon-12 atoms, the amount of material in the system is 1 mole. The ratio of the moles of constituent gas to the total moles of mixed gas, expressed as xi
