Question

What is the vapour density of hydrogen?​

Answer 1

Answer:

here your answer

Explanation:

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. vapour density = molar mass of gas / molar mass of H2.

Answer 2

The vapour density of hydrogen is as follows:

• The weight of a vapour or gas correlated to the weight of an equal volume of air is a manner of the density of the vapour or gas. Materials lighter than air have vapour densities less than one.
• Vapour density of gas = mass of n molecules of gas/mass of n molecules of hydrogen.
• vapour density of H2 = molar mass of hydrogen gas / 2.016 vapour density = 1⁄2 × molar mass.
• Gaseous hydrogen has a density of 0.00523 lb/ft3,
• To calculate a compound's vapour density solely divide the molecular weight of the mixture by the molecular weight of air. This will give numerical importance that can be correlated to the air's value of one.
