1.3.2 Mixture of Gases
ОглавлениеFor a mixture of N gaseous components, the total mass and total moles are, respectively,
where
mi: mass of the ith component
ni: amount of substance in moles of the ith component
If the molecular mass of ith component is μi, then
(1.40)
The mass fraction (or mass concentration) is
(1.41)
Similarly, the mole fraction (or mole concentration) can be found as follows:
(1.42)
The molar mass of the total mixture is
(1.43)
From Eqs. (1.40), (1.41), and 1.42,
(1.44)
