如何计算Mole Fraction

learn.whatIsHeading

Mole fraction (χ) = moles of component / total moles; used in colligative properties, partial pressure, solution equilibria.

分步指南

  1. 1Input moles of each component
  2. 2Calculate mole fraction of each
  3. 3Apply in Raoult's law, Henry's law, etc.

例题解析

输入
Solution: 1 mol ethanol, 4 mol water
结果
χ_ethanol = 0.2, χ_water = 0.8

常见错误注意事项

  • Confusing mass and mole percentages
  • Not summing to 1.0 for all components

常见问题

How does mole fraction differ from mass fraction?

Mole: counted particles; mass: weighs compounds; related by molar mass.
