Question
What will be the vapor pressure at 25 degree C of a 30.0% (by mass) solution of glucose, C6H12O6 (a non-electrolyte-molar mass = 180 g/mol), in water? The vapor pressure of water at 25 degree C is 23.8 mm Hg.
P<sub>solvent</sub> = X<sub>solvent</sub>P<sup>o</sup><sub>solvent</sub>.
You will need to calculate the mol fraction, X of the solvent in 30.0% by mass glucose.
