A liquid mixture at $30C$ contains $50\%$ n$-$heptane and $50\%$ n$-$octane. A $100$ mole

of this liquid mixture will be subjected to a differential distillation at $1$atm. Determine the

mole fraction in the distillate if the process will be stopped when the mole fraction of the

MVC reaches $0\mathrm{.}33.$ Equilibrium Data is provided on the next page.
