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:

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
