### What is the vapour pressure of toluene at 30 C?

At 30.0°C the vapor pressure of pure toluene and pure benzene are 36.7 and 118.2 torr, respectively.

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 partial pressure of toluene?

The vapour pressure of pure benzene is 119 torr; that of toluene is 37 torr at the same temperature.

## What is the vapor pressure of toluene at 25 C?

The vapor pressure at 25◦C of benzene is 94.6 torr and that of toluene is 29.1 torr. Q.

Does toluene have a high vapor pressure?

It has a sweet, pungent benzene like odor. Toluene has a molecular weight of 92.14 g mol−1. At 25 °C, toluene has a solubility in water of 526 mg l−1, an estimated vapor pressure of 28.4 mm Hg and a Henry’s Law Constant of 6.64 × 10−3 atm-m3 mol−1(USEPA, 2011).

What is the formula of vapour pressure of solution?

As the solution is formed by dissolving urea in water, so by general formula to calculate the vapour pressure of the solution the equation should be ${P_{sol}} = {X_{urea}} \times P_{urea}^o + {X_{water}} \times P_{water}^o$but urea is a non-volatile compound so it will not exert any vapour pressure.

### What is the formula of vapour?

What is vapour and vapour pressure?

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

What is liquid vapour pressure?

Vapour pressure can be defined as pressure formed by the vapor of the liquid (or solid) over the surface of the liquid. This pressure is formed in a thermodynamic equilibrium state in a closed container at a certain temperature. Liquid’s evaporation rate is identified by the equilibrium vapor pressure.
