Definition.—We have seen that the molecular weight of a compound, as well as of most elements, is obtained from the vapor density by doubling the latter. An Introduction to Chemical Science

P has an atomic weight of 31, while its vapor density is 62. An Introduction to Chemical Science

What will the relative humidity be that evening when the temperature has dropped to 10.0ºC , assuming constant water vapor density? College Physics for AP Courses 2015-08-12T00:00:00Z

Its molecule must consist of 4 atoms, each half the size of the H atom, The vapor density of As is 150, the atomic weight 75. An Introduction to Chemical Science

Hg has an atomic weight of 200, a vapor density of 100. An Introduction to Chemical Science

Molecular Symbols.—From the vapor density of the gases— column 2—we obtain their molecular weight— column 3. An Introduction to Chemical Science

Ozone has an atomic weight of 16, a vapor density 24. An Introduction to Chemical Science

Law of Diffusion of Gases.—The diffusibility of gases varies inversely as the square roots of their vapor densities. An Introduction to Chemical Science

In case of a compound gas, half the molecular weight must be taken for the vapor density; e.g. dif. An Introduction to Chemical Science

Its vapor density at 1,000 degrees is 32; hence its molecular weight is 64, i.e. vapor density x 2; and there are 2 atoms in its molecule at that temperature, molecular weight / atomic weight. An Introduction to Chemical Science

Molecular and Atomic Volumes.—We thus see that vapor density and atomic weight are obtained in two quite different ways. An Introduction to Chemical Science

Its vapor density is 150, which gives 300 for the molecular weight, while its least combining or atomic weight is 75. An Introduction to Chemical Science

Compare the vapor density and the atomic weight of Hg, and explain. An Introduction to Chemical Science

If the volumes of gases vary as above, it is evident that their vapor densities must vary inversely. An Introduction to Chemical Science

The vapor density of a gas is inversely proportional to the temperature. An Introduction to Chemical Science

In the case of elements the two are usually identical, i.e. with the few whose vapor density is known; but this is not always true, and it leads to interesting conclusions regarding atomic volume. An Introduction to Chemical Science

Also, the vapor density is directly proportional to the pressure, since a liter of any gas under a pressure of one atmosphere is reduced to half a liter under two atmospheres. An Introduction to Chemical Science

No heat or condensation takes place when four measures of N are brought in contact with one of O. It cannot then be N4O, for the vapor density of N4O would be 36—i.e. An Introduction to Chemical Science

Compare the vapor density of I with that of Br and of Cl. An Introduction to Chemical Science

To obtain the vapor density of any compound from the formula, we have only to divide its molecular weight by two. An Introduction to Chemical Science

In O both vapor density and atomic weight are 16. An Introduction to Chemical Science

But in practice the formula is obtained from the vapor density, and hence the method there given has to be reversed. An Introduction to Chemical Science
