Two alcohols, isopropyl alcohol and propyl alcohol, have the same molecular formula, C3H8O. A solution of the two that is two-th
iris [78.8K]

Answer:

1.

Since both components of these solutions have the same molar mass, mole fractions would be the same as mass fractions.

0.110 atm = (2/3)(Pi) + (1/3)(Pn) [1]

0.089 atm = (1/3)(Pi) + (2/3)(Pn) [2]

2*[1] - [2]:

(2)(0.110) - 0.089 atm = Pi

Pi = 0.131 atm

2*[2] - [1]:

(2)(0.089) - 0.110 atm = Pn

Pn = 0.068 atm

2.

The hydroxyl (-OH) group on the end of a longer 1-propanol molecule makes it more polar than IPA. It follows that the intermolecular forces between 1-propanol are stronger than those of IPA and thus the vapor pressure of 1-propanol should be lower than IPA.
