Define mole fraction.
Answers
Explanation:
The mole fraction is also called the amount fraction.It is identical to the number fraction, which is defined as the number of molecules of a constituent Ni divided by the total number of all molecules Ntot. The mole fraction is sometimes denoted by the lowercase Greek letter χ (chi) instead of a Roman x. For mixtures of gases, IUPAC recommends the letter y.
The National Institute of Standards and Technology of the United States prefers the term amount-of-substance fraction over mole fraction because it does not contain the name of the unit mole.
Answer:-
Mole fraction is denoted by X
Defination:-
One of the unit of Concentration is mole fraction,and mole fraction is equal to the number of moles of a component divided by the total number of moles of a solution.
Mole fraction of solute
a) Mole fraction of solute is define by number of moles of solute divided by the total numbers of moles of solution.
=> X (solute)
=(moles of solute)/(total moles of solution)
Mole fraction of solvent
b) Mole fraction of solvent is define by number of moles of solvent divided by the total numbers of moles of solution.
=> X (solvent)
=(moles of solvent)/(total moles of solution)
