At 100 0c the vapor pressures of pure n-hexane (subscript 1) and pure n-octane (subscript 2) are, respectively, p10 = 1836 torr and p20 = 354 torr . a certain liquid mixture of these two compounds has a vapor pressure of 668 torr at the same temperature.
a) what is the mole fraction x1 of n-hexane in the liquid mixture.
b) what is the mole fraction y1 of n-hexane in the vapor phase above the mixture?
c) what is the partial pressure p2 of n-octane in the vapor phase?
