How to Calculate Mole Fraction
Formula
X_A = n_A / (n_A + n_B)
Mole fractions are dimensionless and always sum to 1.
计算示例
A mixture of 2 mol ethanol and 3 mol water.
- Total moles = 2 + 3 = 5
- X_A = 2 / 5 = 0.4
- X_B = 3 / 5 = 0.6
X_A = n_A / (n_A + n_B)
Mole fractions are dimensionless and always sum to 1.
