What is the vapor pressure of ethanol at 45 C?
Ethanol has a vapor pressure of 165 mmHg at 45 C and a heat of vaporization of 38.56 kj/mo.
What is the vapor pressure calculator?
Vapor Pressure Calculator is a free online tool that displays the vapor pressure of a solid or liquid at a given temperature. BYJU’S online vapor pressure calculator tool makes the calculation faster and it displays the vapor pressure in a fraction of seconds.

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 vapor pressure of ethanol at 40 C?
The vapor pressure of ethanol at 40 °C is 150 Torr. The heat of vaporization for ethanol is 39.0 kJ/mol.
What is the vapor pressure of ethanol at 19 C?
The vapor pressure of ethanol (C2H5OH) at 19? C is 40.0 torr.
What is the highest vapor pressure?
At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, 760 Torr, 101.325 kPa, or 14.69595 psi. For example, at any given temperature, methyl chloride has the highest vapor pressure of any of the liquids in the chart.
What is an example of vapor pressure?
Vapor pressure is the pressure exerted by a liquid back on the atomosphere. Vapor pressure depends on the nature of the liquid and the temperature. An example is water’s vapor pressure, which happens to be relatively low because of the hydrogen bonding between the water molecules.
What is lower vapor pressure?
Vapor pressure lowering is a colligative property of solutions. The vapor pressure of a pure solvent is greater than the vapor pressure of a solution containing a non volatile liquid. This lowered vapor pressure leads to boiling point elevation.
