Mole fraction (D) has no units.
Mole fraction is a dimensionless quantity that represents the ratio of the number of moles of a particular component to the total number of moles in a mixture. It is expressed as a decimal or fraction and does not have any units associated with it.
On the other hand:
A. Molarity (M) is expressed in units of moles per liter (mol/L).
B. Normality (N) is expressed in units of equivalents per liter (eq/L).
C. Molality (m) is expressed in units of moles of solute per kilogram of solvent (mol/kg).
