【Abstract】 The vapor pressure of alcohol and saturated solution of magnesium chloride in alcohol was respectively measured at the different temperature(340K to 360K).According to the principle of thermodynamics,some equations for calculating the activity from vapor pressure or boiling point were derived.There are a few differences between the results calculated by the different equations.更多还原
