Relative Volatility using Mole Fraction Solution

Follow our step by step solution on how to calculate Relative Volatility using Mole Fraction?

FIRST Step Consider the formula

α = \frac{\frac{y Gas}{1 - y Gas}}{\frac{x Liquid}{1 - x Liquid}}

Next Step Substitute values of Variables

∴

α = \frac{\frac{0.3}{1 - 0.3}}{\frac{0.51}{1 - 0.51}}

Next Step Prepare to Evaluate

∴

α = \frac{\frac{0.3}{1 - 0.3}}{\frac{0.51}{1 - 0.51}}

Next Step Evaluate

∴

α = 0.411764705882353

LAST Step Rounding Answer

∴

α = 0.4118
