Ideal Gas Mixtures
Ideally the ratio of partial pressures is the same as the ratio of molecules. That is, the mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure or the moles of the component:
and the partial pressure of an individual gas component in an ideal gas can be obtained using this expression:
| where: | |
| = mole fraction of any individual gas component in a gas mixture | |
| = partial pressure of any individual gas component in a gas mixture | |
| = moles of any individual gas component in a gas mixture | |
| = total moles of the gas mixture | |
| = total pressure of the gas mixture |
The mole fraction of a gas component in a gas mixture is equal to the volumetric fraction of that component in a gas mixture.

Famous quotes containing the words ideal, gas and/or mixtures:
“The air was so elastic and crystalline that it had the same effect on the landscape that a glass has on a picture, to give it an ideal remoteness and perfection.”
—Henry David Thoreau (1817–1862)
“Shielded, what sorts of life are stirring yet:
Legs lagged like drains, slippers soft as fungus,
The gas and grate, the old cold sour grey bed.”
—Philip Larkin (1922–1986)
“If thought makes free, so does the moral sentiment. The mixtures of spiritual chemistry refuse to be analyzed.”
—Ralph Waldo Emerson (1803–1882)
