If the vapor pressure of an aqueous solution of ethylene, Ask an Expert

Academics

If the vapor pressure of an aqueous solution of ethylene glycol C2H6O2 (62.06844 g/mol) was found to be 52.3 torr at 39.8 degrees C, calculate the grams of ethylene glycol used to make this solution if 215.00 mL H2O was used as solvent? Note: pure H2O has vapor pressure of 54.74 torr and density of 0.992 g/mL.

Then Calculate the freezing point of the ethylene glycol solution described above if the freezing point constant for the solvent is Kf=1.86 deg C kg/mol.
