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.
Sorry, something has gone wrong. Best Answer: 66 2/3% = 2/3 as a fraction it's a common % and fraction so important to know. but if you forget, or have to change ANY percent to a fraction, just remember: % means 1/100 so.. . 66 2/3 % = 66 2/3 X 1/100 change to improper fraction: 200/3 X 1/100 = 200/300 = 2/3 that's it! ;).nswers.
