Which option gives the most correct statement for mole fraction?

Answer and explanation

Correct answer: Ratio of moles of a component to total moles

The mole fraction of component i is defined as xᵢ = nᵢ/Σn, meaning the moles of that component divided by the total moles of every component in the mixture. It is a dimensionless quantity, and all component mole fractions add to one. Thus option A is correct. Option B describes a mass-per-volume concentration, while C and D are not definitions of mole fraction.
