A binary AB liquid mixture containing 30 mol% A is subjected to differential (Rayleigh) distillation at atmospheric pressure in order to recover 60 mol% A in the distillate. Assuming a constant relative volatility αAB=2.2. the average composition of the collected distillate is ______ mol% A (rounded off to nearest integer).
