Answer: The vapor pressure of the solution is 55.2 torr
Explanation:
and
where, x = mole fraction in solution
= pressure in the pure state
According to Dalton's law, the total pressure is the sum of individual pressures.
x = mole fraction =
Given : 299 g of toluene and 391 g of benzene.
moles of toluene =
moles of benzene=
Total moles = moles of solute (toluene) + moles of solvent (benzene) = 3.25 + 5.01 = 8.26
= mole fraction of benzene =
=mole fraction of toluene = (1-0.39) = 0.61
Thus the vapor pressure of the solution is 55.5 torr
