Molar ratio in a mixture of water and absolute alcohol is `0.2`. The mole fraction ratio of alcohol and water is

What is absolute alcohol ?

The percentage of ethyl alchol by weight is 46% in a mixture of ethanol and water. The mole fraction of alcohol in this solution is

The alcohol having least solubility in water is

138 g of ethyl alcohol is mixed with 72 g of water. The ratio of mole fraction of alcohol to water is

The boiling point of an azeotropic mixture of water and ethyl alcohol is less than that of the theoretical value of water and alcohol mixture. Hence the mixture shows

The boiling point of an azeotropic mixture of water and ethyl alcohol is less than that of the theoretical value of water and alcohol mixture. Hence the mixture shows

The boiling point of an azeotropic mixture of water and ethyl alcohol is less than that of the theoretical value of water and alcohol mixture. Hence the mixture shows

A mixture of ethyl alcohol and propyl alcohol has a vapour pressure of 300 mm at 300 K. The vapour pressure of pure propyl alcohol is 200 mm. If the mole fraction of ethyl alcohol in the mixture is 0.375, then the vapour pressure (in mm) of pure ethyl alcohol at the same temperature will be :

A solution is prepared by dissolving 46 g of ethyl alcohol in 90 g of water. The mole fraction of ethyl alcohol in this solution is:

A mixture of ethyl alcohol and propyl alcohol has a vapour pressure of 290 mm at 300K. The vapour pressure of propyl alcohol is 200 mm. if the mole fraction of ethyl alcohol is 0.6 , its vapour pressure (in mm) at the same temperature will be
