plz solve only ii and iii asap.Thanks

Question 2 For a binary mixture of Acetone and Hexane (i) If the mixture forms an azeotrope boiling at 49.6 C at 1 atm pressure, with a composition x1 = 0.625. Calculate the van Laar and the Margulus Coefficients for the system and compare them to the values published in literature, (ii) Using the van Laar and the Margulus Coefficients found in literature, determine the dew point and the bubble point for ten different compositions (iii) Use the data developed in part 2 to determine the van Laar and the Margulus Coefficients. Comment on your results. (iv) Using the van Laar and the Margulus Coefficients found in literature, determine the equilibrium pressures of ten different liquid compositions, (V) Use the data developed in part 4 to determine the van Laar and the Margulus Coefficients. Comment on your results. (vi) Discussions of the overall results and what you have learnt
