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.
Calculator 2a is a word problem version of the equation Y/X = P% in 2b so they are solved the same way. This calculation is converting a ratio or fraction to a percentage. For example, how to solve for the percentage of one number to another: 1  15 is what percent 150? in equation form is 15/150 = P%.2  15/150 = 0.10. 3  We now need to convert the decimal to an percentage so we end up with a percentage.alculator 2a is a word problem version of the equation Y/X = P% in 2b so they are solved the same way.
