Noun
mole fraction (plural mole fractions)
(chemistry) the ratio of the number of moles (not the animal) of one component of a mixture to the total number of moles
Air is typically assumed to have a mole fraction composition of 0.7812 molecular nitrogen, 0.2095 molecular oxygen and 0.0093 argon. Source: Internet
At about 0.8 mole fraction fayalite, olivine transforms directly to ringwoodite over the pressure range convert. Source: Internet
At a given barometric pressure but independent of temperature, the dew point indicates the mole fraction of water vapor in the air, or, put differently, determines the specific humidity of the air. Source: Internet
Mole fraction main The mole fraction is defined as the amount of a constituent (in moles) divided by the total amount of all constituents in a mixture : : The SI unit is mol/mol. Source: Internet
If the pressure rises without changing this mole fraction, the dew point will rise accordingly; Reducing the mole fraction, i.e., making the air less humid, would bring the dew point back down to its initial value. Source: Internet
It composes about 18.2 ppm of air by volume (this is about the same as the molecular or mole fraction), and a smaller fraction in Earth's crust. Source: Internet
