Ethylene glycol (HOCH2CH2OH) is used to increase the boiling point of radiator fluid by lowering its
vapor pressure. The vapor pressure of pure water at 100 ºC is 760.0 mmHg. Calculate the vapor
pressure of an aqueous solution containing 40.0% ethylene glycol by mass at 100 ºC. (M.W. of
ethylene glycol is 62.7 g/mol)
