What is the mole fraction in instantaneous distillate if: Moles of liquid in residue at start W0= 1000 Moles of liquid in residue at end W= 500 Mole fraction in liquid at start X0 = 0.7 Mole fraction in liquid at end X= 0.4

What is the mole fraction in instantaneous distillate if: Moles of liquid in residue at start W0= 1000 Moles of liquid in residue at end W= 500 Mole fraction in liquid at start X0 = 0.7 Mole fraction in liquid at end X= 0.4 Correct Answer 1

XD = W0X0 –WX/W0-X, hence Xd= 1.
