Mole fraction (χ) = moles of component / total moles; used in colligative properties, partial pressure, solution equilibria.
ステップバイステップガイド
- 1Input moles of each component
- 2Calculate mole fraction of each
- 3Apply in Raoult's law, Henry's law, etc.
解いた例
入力
Solution: 1 mol ethanol, 4 mol water
結果
χ_ethanol = 0.2, χ_water = 0.8
避けるべきよくある間違い
- ✕Confusing mass and mole percentages
- ✕Not summing to 1.0 for all components
よくある質問
How does mole fraction differ from mass fraction?
Mole: counted particles; mass: weighs compounds; related by molar mass.
