ratio of moles of one component to total number of moles
The number of moles of a particular substance expressed as a fraction of the total number of moles. Back to .
An expression of the number of moles of a compound divided by the total number of moles of all compounds present.
The number of moles of a component of a mixture divided by the total number of moles in the mixture.
Concentration of a substance in a mixture measured as moles of the substance per mole of complete mixture.
In a gas mixture, the ratio of the partial pressure of a gas to the total pressure of the mixture. Compare mixing ratio, specific humidity.
In chemistry, the mole fraction of a component in a mixture is the relative proportion of molecules belonging to the component to those in the mixture, by number of molecules. It is one way of measuring concentration. It provides the most symmetrical way of representing thermodynamic functions of mixtures.
