Calculate the mole fraction of a compound in a vapor using the formula y = (ά * x) / {1 + (ά -1) * x}, where "ά" is the relative volatility, "x" is the mole fraction of the substance in the liquid and "y" is the mole fraction of the substance in the vapor.
In a simple distillation, a homogeneous liquid mixture is boiled.
The rising vapor then enters the inner chamber of a water-cooled condenser.
The vapor condenses to a liquid, called the distillate, which is then collected in a separate vessel.
