A petroleum company separates benzene (78 g/mol) and n-octane (114 g/mol) by distillation. In one run, the starting solution was 15% benzene and 85% n-octane by mass at 25 ^$\circ$ C. In the liquid, the mole ratio of benzene to n-octane was ________, and in the vapor it was ________. The vapor pressures for benzene and n-octane at this temperature are 11 torr and 95 torr, respectively.
