A well-agitated mixture consists of equal moles of toluene and water at 100 oC. Toluene and water can be considered to be totally immiscible with one another. The vapor pressure of toluene is 556 mm Hg at 100 oC. What is the mole fraction of toluene in the vapor in equilibrium with this liquid mixture at 100 oC

the answer is definitely c.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
