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.
OK Sara...not sure what you mean by compatible numbers but you said estimate the quotient..so here goes. 7 1/12 is approximately = 7 and 1 1/3 is approximately = 1 so quotient would be 7 as an estimate. Now, converting from mixed numbers to improper fractions you get 85/12 divided by 4/3.
