A continuous fractionation column is to be designed to separate $30,000$ kg$/$h of a mixture of $40\%$ benzene and $60\%$ toluene into a distillate product containing $97\%$ benzene and a residual product of $98\%$ toluene. These percentages are expressed by weight. Determine the molar flow of the mixture

Question $5$ Select one:

to$.$

$196\mathrm{.}6$ kgmol$/$h

b$.$

$350$ kgmol$/$h

c$.$

$153\mathrm{.}4$ kgmol$/$h

d$\mathrm{.}35\mathrm{.}0$ kg mol$/$h
