Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen gas .
Molecular mass ( m): A molecular mass is the sum of the mass of all the atoms in a molecule. Adding the atomic masses of all atoms in a molecule gives molecular mass. Vapor density: Vapor density is the density of vapor in relation to the density of vapor of hydrogen. It is having a relative value. It is unitless. Relation:
What is Vapour Density: Explain the Vapour density of mixture, Degree of dissociation, vapour density formula and calculation at Aakash
Jul 30, 2023 · The formula for vapor density is: vd = m/V or vd = MW/2.016 (for hydrogen) or vd = MW/28.97 (for air) where vd is vapor density, m is the mass of the substance, V is the volume of the substance, MW is the molar mass of the substance, and 2.016 and 28.97 are the molar masses of hydrogen and air, respectively.
Aug 19, 2023 · Vapor density, also known as relative vapor density, is a measure of the density of a gas or vapor compared to the density of a reference gas. The reference gas is typically air, which is...

Jun 28, 2024 · The density of a gas or vapour relative to hydrogen, oxygen, or air. Taking hydrogen as the reference substance, the vapour density is the ratio of the mass of a particular volume of a gas to the mass of an equal volume of hydrogen under identical conditions of pressure and temperature.
Density of a gas relative to hydrogen is called its vapour density. Mathematically, it can be expressed as: V a p o u r D e n s i t y = ρ g a s ρ H 2. Let us consider that in a container of capacity 'V' litres, we have 'n' moles of H 2 gas and in another container of capacity 'V' litres, we have 'n' moles of a gas of molecular mass 'M'.
