In chemistry, the mole fraction or molar fraction, also called mole proportion or molar proportion, is a quantity defined as the ratio between the amount...

for molality is mol/kg. The mole fraction x i {\displaystyle x_{i}} is defined as the amount of a constituent n i {\displaystyle n_{i}} (in moles) divided...

are obtained from the definitions of the molalities and of the other compositional quantities. The mole fraction of solvent can be obtained from the definition...

of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure...

composition of a mixture in a dimensionless size; mole fraction (percentage by moles, mol%) and volume fraction (percentage by volume, vol%) are others. When...

dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others. Volume percent is the concentration of...

the molar mass of constituent i {\displaystyle i} . The conversion to mole fraction x i {\displaystyle x_{i}} is given by x i = c i M ¯ ρ , {\displaystyle...

mole fraction in the mixture. In consequence, the relative lowering of vapor pressure of a dilute solution of nonvolatile solute is equal to the mole...

distinguished from "mole fraction", which should be the number of moles (molecules) of the substance of interest divided by the total number of moles (molecules)...

mass fraction (in commercial contexts often called weight fraction), by mole fraction (fraction of atoms by numerical count, or sometimes fraction of molecules...
