...Chemistry " inclined to the atomic theory. English edition, translated by H. Watts, vol. ip 42. s " Equal volumes of all gases under the same conditions of temperature and pressure contain equal cumbers of molecules.' Berthelot and of Kolbe, was the instrument which served to build up modern...

...is based on the molecular theory. It is more general, and includes the other two. It declares that equal volumes of all gases, under the same conditions...and pressure, contain the same number of molecules. Liquids are distinguished from gases chiefly in having a definite surface. Their particles have the...

...number of simple gases. But if equal volumes of these gases, measured, let it be well understood, under the same conditions of temperature and pressure, contain the same number of atoms, it is evident that the weights of these equal volumes should represent the weights of the atoms....

...not fail to suggest to Ampere the following hypothesis : EQUAL VOLUMES OF ALL GASES, MEASURED UNDER THE SAME CONDITIONS OF TEMPERATURE AND PRESSURE, CONTAIN THE. SAME NUMBER OF MOLECULES OF THE SUBSTANCE. 382. The following illustration may serve to make this clearer: Take three glass...

...Cn+8HN03=3 Cn(N03)2+2 NO+ 4H..O. 7. Equal volumes of all substances in the gaseous state, and under the same conditions of temperature and pressure contain the same number of molecules. By means of this principle the atomic weights of elements and the molecular formulae of compounds have...

Avogadro's hypothesis that equal volumes of all gases under the same conditions...and pressure contain the same number of molecules was suggested by a study of the physical properties of gases and a comparison of the weights of equal...

...attraction, must have taken too small a quantity as representing the volume of the molecules. Since all gases under the same conditions of temperature and pressure contain the same number of molecules in a given volume, the result found above for the mean distance, viz. 25 x 10~7 is of general application....
