Glycerin (c3h8o3) is a nonvolatile liquid. what is the vapor pressure of a solution made by adding 170 g of glycerin to 337 ml of h2o at 40.0°c?
the vapor pressure of pure water at 40.0°c is 55.32 torr and its density is 0.992 g/cm3.

mass water = 347 x 0.992 = 344.2 g

moles water = 344.2 g / 18.02 g/mol= 19.1

moles C3H8O3 = 164 g / 92.097 g/mol= 1.78

mole fraction water = 19.1 / 19.1 + 1.78 = 0.915

p = 0.915 x 54.74 = 50.07 torr

Explanation:

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
