Vapour Phase Mole Fraction using Modified Raoult's Law in VLE evaluator uses Mole Fraction of Component in Vapor Phase = (Mole Fraction of Component in Liquid Phase*Activity Coefficient in Raoults Law*Saturated pressure)/Total Pressure of Gas to evaluate the Mole Fraction of Component in Vapor Phase, The Vapour Phase Mole Fraction using Modified Raoult's Law in VLE formula is defined as the ratio of the product of the liquid phase mole fraction, activity coefficient and the saturated pressure to the total pressure of mixture or solution. Mole Fraction of Component in Vapor Phase is denoted by yGas symbol.
