Given information
The mass percent of naphthalene in the solution is .
The vapor pressure of pure hexane at is .
Step-by-step explanation
Step 1.
The mass percent of the naphthalene is mean of naphthalene is present in the solution.
The mole fraction of water in the naphthalene solution is calculated by the formula,
(considered as equation 1)
Where,
-
is the mole fraction of hexane.
-
is the number of moles of hexane in the solution.
-
is the number of moles of naphthalene 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.
