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.
And divide the percentage by 100 to get the decimal. So: 1)26/100 = 13/50 26% = 0.26 To get a fraction from a decimal you: Put the decimal out of a 100 then cancel To get a percentage out of a decimal put the percent sign in behind the decimal So: 2)0.13 = 13/100 0.13 = 13%. kcruza95 Â· 7 years ago.
