Formel
## How to Calculate Mole Fraction ### Formula **X_A = n_A / (n_A + n_B)** Mole fractions are dimensionless and always sum to 1.
Lösungsbeispiel
A mixture of 2 mol ethanol and 3 mol water.
- 01Total moles = 2 + 3 = 5
- 02X_A = 2 / 5 = 0.4
- 03X_B = 3 / 5 = 0.6
Häufig Gestellte Fragen
What is mole fraction?
Mole fraction is the ratio of moles of one component to the total moles in the mixture. It ranges from 0 to 1.
Why must mole fractions sum to 1?
Because they represent proportions of the whole mixture.
How is mole fraction related to partial pressure?
By Dalton's law, partial pressure of a gas equals its mole fraction times total pressure: P_i = X_i × P_total.
