About Mole Fraction

Mole fraction (χ) is the ratio of the number of moles of a component to the total number of moles in the mixture. It's a dimensionless quantity.

χᵢ = nᵢ / Σnᵢ

Where:

  • χᵢ = Mole fraction of component i
  • nᵢ = Moles of component i
  • Σnᵢ = Total moles in the mixture

Key properties:

  • Sum of all mole fractions equals 1
  • Temperature-independent
  • Used in Raoult's law and colligative properties
  • Common in gas mixtures and solutions

Mole fraction is particularly useful in thermodynamics, phase equilibria, and understanding solution behavior.
