Vapour Density (Noun)
Meaning
The density of a gas relative to the density of hydrogen.
Classification
Nouns denoting attributes of people and objects.
Examples
- The vapour density of the unknown gas was determined to be 11.2, indicating its molecular weight was roughly 22.4 times that of hydrogen.
- Vapour density measurements are a relatively simple means to determine the molecular weight of a gas.
- Using Graham's law of diffusion and the measured vapour density of the sample, researchers estimated the rate at which the components would separate.
- Historically, the vapour density of gases was determined using a technique known as Dumas' method, developed by French chemist Jean-Baptiste Dumas.
- Comparing the calculated and experimental vapour density values revealed an inconsistency that required further investigation into the gas composition.
