Consider two compounds, A (M.W. = 93.1 g/mol) and B (86.2 g/mol), forming a partially miscible liquid-liquid mixture. Then, mixing 42.8 g of A and 75.2 g of B formed two separate liquid phases. The mole fraction of A in one phase is 0.308 and 0.618 on the other phase. Determine the masses of A and B in each phase. Note: Use binary phase diagram

Answers:

mass A alpha = 33.5 g

mass A beta = 9.12 g

mass B alpha = 69.8 g

mass B beta = 5.26 g
