...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...

...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...

...taken together with others relating to the physical properties of gases, led Avogadro to the conception that equal volumes of all gases under the same conditions...and pressure contain the same number of molecules. This is known as Avogadro's hypothesis. It has been tested in a great many ways, but has always asserted...

...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....

...as follows: Equal volumes of all substances, simple and compound, in the state of a gas when under the same conditions of temperature and pressure contain the same number of molecules. Hence each of these molecules occupies an equal space. It is true that, as these formulas are used,...

...it is usual to state the above results in the form which is known as Avogadro's Law, which asserts that equal volumes of all gases, under the same conditions...and pressure, contain the same number of molecules. A given vessel, when full of oxygen gas at the atmospheric pressure, will contain the same number of...
