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 of a constituent substance, n i (expressed in unit of moles, symbol mol), and the total amount of all constituents in a mixture, n tot (also expressed in moles):
8 Ιαν 2022 · The mole fraction is a dimensionless number. The sum of all of the mole fractions equals 1. The symbol for mole fraction is the capital letter X or the lowercase Greek letter chi ( χ ). The terms “amount fraction” or “amount-of-substance fraction” mean the same as mole fraction.
The mole fraction is: moles of target substance divided by total moles involved. The symbol for the mole fraction is the lower-case Greek letter chi, χ. You will often see it with a subscript: χ solute is an example. Example #1: 0.100 mole of NaCl is dissolved into 100.0 grams of pure H 2 O.
Στη χημεία, κλάσμα mole X ή γραμμομοριακό κλάσμα ή μοριακό κλάσμα είναι ένας τρόπος έκφρασης της σύστασης ενός αέριου ή υγρού διαλύματος. Ως γραμμομοριακό κλάσμα X i ενός συστατικού i σε ένα μίγμα, ορίζεται το κλάσμα με αριθμητή τα moles n i του συστατικού i στο μίγμα και παρονομαστή το άθροισμα των moles n ολ όλων των συστατικών του μίγματος.
Mole fraction of every solute = number of moles of that solute/ the entire number of moles of all solutes and also the solvent. It is just like the amount fraction. The lowercase Greek letter χ (chi) rather than a Roman x are the notations of mole fraction.
Mole fraction \(X\) is the ratio of moles of one substance in a mixture to the total number of moles of all substances. For a mixture of two substances, \(\ce{A}\) and \(\ce{B}\), the mole fractions of each would be written as follows:
The mole fraction is sometimes denoted by the lower case Greek letter χ (chi) instead of a Roman x. Mole fractions are dimensionless numbers. Other ways of representing concentrations, e.g., molarity and molality, yield dimensional quantities (per litre, per kilogram, etc.).
