A mixture of ethanol and 1-propanol behaves ideally at 36 C and is in equilibrium with its vapor. If the mole fraction of ethanol in the solution is 0.63, calculate its mole fraction in the vapor phase at this temperature. (The vapor pressures of pure ethanol and 1-propanol at 36 C are 108 and 40.0 mmHg, respectively.)
Chromatography is all about intermolecular forces. Name two intermolecular forces that are involved in chromatography and the roles that they play during separation.
At 25?°C, the vapor pressure of diethyl ether is higher than the vapor pressure of its isomer n-butanol, because A. diethyl ether has a higher density than n-butanol.
