An amino acid is recovered from a toluene solution by using pure water in a one-stage batch liquid-liquid extraction process. The volume of the feed (toluene solution) is 4 L, with a concentration of 0.005 M amino acid. The volume of water is 1 L. Calculate the yield after the extraction. The equilibrium equation is: Y=2000 X2

Y = conc. of amino acid in water,

X = conc. of amino acid in toluene.
