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.
