Given information
The mass of heptane in the mixture is 
The vapor pressure of pure heptane at 
The mass of octane in the mixture is
The vapor pressure of pure octane at 
Step-by-step explanation
The mole fraction of water in the heptane solution is calculated by the formula,
(considered as equation 1a)
And the mole fraction of octane is calculated by the formula,
(considered as equation 1b)
Where,
-
is the mole fraction of octane.
-
is the mole fraction of heptane.
-
is the number of moles of octane in the solution.
-
is the number of moles of heptane in the solution.
The vapor pressure of a solution is calculated by using the formula,
(considered as equation 2)
Where,
-
is the vapor pressure of solution.
-
is the vapor pressure of pure solvent.
-
is the mole fraction of solvent in the solution.
