A company wishes to distill a 0.830 mole fraction ethanol (0.170 mole fraction water) solution. To aid in the distillation process, a 0.950 mole fraction benzene (0.050 mole fraction water) mixture containing fresh benzene and a recovered benzene solution is added.
Pi cannot be a fraction but 22/7 is a good approximation. 22/7 = 3.1428; the first 2 digits to the right of the point are correct.Zeta1 Â· 8 years ago.
