What is the vapor pressure of C6H6?

The vapor pressure of benzene (C6H6) and toluene (C7H8) at 25 degrees Celcius are 95.1 and 28.4 mm Hg, respectively. A solution is prepared with a mole fraction of toluene of 0.550.

How do you calculate pure vapor pressure?

The vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature multiplied by its mole fraction.

How do you calculate vapor pressure?

In chemistry, vapor pressure is the pressure that is exerted on the walls of a sealed container when a substance in it evaporates (converts to a gas). To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln(P1/P2) = (ΔHvap/R)((1/T2) – (1/T1)).

What is the boiling point of benzene?

The vapour pressure of water at 100∘C is 760 mm.

What is the vapor pressure of pure benzene at 20 C?

At 20 oC the vapor pressure of benzene C6H6 is 75 torr and that of toluene C7H8 is 22 torr.

How do you find the vapor pressure of benzene?

Vapour pressure of a mixture of benzene and toluene is given by P=179XB+92, where XB is the mole fraction of benzene.

What is the vapor pressure of benzene C6H6 at 50 °C?

The vapor pressure of pure benzene C6H6 at 50 °C is 268 torr. How many moles of a nonvolatile solute per mole of benzene is needed to prepare a solution having a vapor pressure of 177.5 torr at 50 °C? UpdateCancel.

What is the mole fraction of non-volatile components in benzene?

The mole fraction of benzene will be: 0.3377 mole fraction non-volatile/0.6623 mole fraction benzene = 0.510 moles of non-volatile component per mole of benzene to obtain a vapor pressure of benzene of 177.5 torr. Now, this answer assumes that this mixture of two components behave ideally.
