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.
i think that you first have to see what the whole number is on the left of the decimal which is 8 and then with the .333 find the fraction which is 1/3 because 1/3 equals .333 as a decimal and so your answer would be 8 1/3.
