Reduced temperature for benzene is `0.7277` and its reduced volume is `0.40`. Calculated the reduced pressure of benzene.

Reduced temperature and reduced volume of benzene are 0.7277 and 0.40 respectively Calculate reduced pressure of benzene .

The mole fraction of benzene in a solution in toluene is 0.40. Calculate the weight per cent of benzene in the solution.

The temperature of a gas filled in closed vessel reduces by 1^@ C . Calculate the ratio of change in pressure to the original pressure of the gas.

The temperature of a gas filled in closed vessel reduces by 1^@ C . Calculate the ratio of change in pressure to the original pressure of the gas.

The correct formula for reduced pressure and reduced volume are

Benzene and toluene form nearly ideal solution. At a certain temperature the vapour pressure of pure benzene and toluene are 150 and 50 torr. respectively. Calculate the vapour pressure of solution containing equal weights of benzene and toluene at this temperature .
