Document Summary
If the number of moles for a = na. If the number of moles for b = nb. If the number of moles for c = nc. Each component in the mixture represents a fraction of the total number of moles in the mixture: ntotal na x = mole fraction = moles of the species total number of moles xa = Note: the sum of the mole fractions is always equal to 1. A gas mixture is composed of 0. 3 mole of oxygen and 1. 2 mole of nitrogen. Find the mole fraction of oxygen and nitrogen. The mole fraction of oxygen = 0. 3 mole / (1. 2 + 0. 3) mole. The mole fraction of nitrogen = 1. 2 mole / (1. 2 + 0. 3) mole. The total mole fraction = 0. 2 + 0. 80 = 1. 0. Since each gas behaves as though it is the only gas, their partial pressure can be expressed as:
