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)
where,we know:-
X (solute) + X (solvent) = 1
i hope it helps you.
