In which concentration term are moles of both solute and solvent useful?
Answer and explanation
Correct answer: Mole fraction
The mole fraction of a component is xᵢ = nᵢ/(nsolute + nsolvent) for a binary mixture. Thus the moles of the selected component and the other component are both needed to calculate the total moles. Percentage concentrations use masses or volumes instead and do not require both mole quantities.
