الكسر المولي ( Mole fraction ) الطب

Mole fraction ما هو الكسر المولي في الكيمياءِ، الكسر المولي لمكوّن ما في خَلِيْط هو التَناسُب النسبيّ من الجزيئات التي تنتمي للمكوّن إلى تلك الموجودة في الخَلِيْط بعدد الجزيئات Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1 In chemistry, the mole fraction or molar fraction (x i) is defined as unit of the amount of a constituent (expressed in moles), n i , divided by the total amount of all constituents in a mixture (also expressed in moles), n tot The mole fraction of a substance in the mixture is the ratio of the mole of the substance in the mixture to the total mole of the mixture. Since it is the ratio of moles to moles, it is a dimensionless quantity. The mole fraction is sometimes called the amount fraction

The modern definition of a mole is as follows: Exactly one mole represents the number of carbon atoms in exactly 12 grams of the carbon-12 isotope. For an atom a mole represents 6.02E 23 atoms. For a molecular compound, one mole represents 6.02E 23 molecules. One could even take it to extremes and say that one mole of bananas is equal to 6.02E. For acid reactions, a 1 M H 2 SO 4 solution will have a normality (N) of 2 N because 2 moles of H + ions are present per liter of solution. For sulfide precipitation reactions, where the SO 4-ion is the important part, the same 1 M H 2 SO 4 solution will have a normality of 1 N Molality definition, the number of moles of solute per kilogram of solvent. See more Diffusion fluxes are determined as relative fluxes of different components in a mixture. If, for example, Ji are the component molar fluxes in a n -componcnt mixture, then one determines the molar convective flux as [7] (1) Jc = n ∑ i = 1Ji, and the diffusive fluxes of each component as.
