...because the volumetric weights of gases are directly proportional to their molecular weights, as all gases at the same temperature and pressure contain the same number of molecules per unit volume. Even dissociation, either of molecules of H2O and CO2 or of molecules of H2 and O2...

...definition of the term molecule as given in par. 12. Avogadro 's rule should read : Equal volumes of all gases at the same temperature and pressure contain the same number of individual particles of matter (not necessarily molecules). See p. 155. The smallest particle of ferric...

...have established the law of volume that has since come to be known as Avogadro's law: Equal volumes of gases at the same temperature and pressure contain the same number of molecules. This is equivalent to stating that all gaseous molecules at the same temperature and pressure are of...

...every rise of 1° C., or -f^f for every 1° F. According to the law oj Avogadro, equal volumes of all gases at the same temperature and pressure contain the same number of molecules. So in equal volumes of solutions having the same osmotic pressure there are the same number of molecules....

...4,800 Density of Gases. — By Avogadro's law the simple fact is established that equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules, and as a consequence it follows that the ratio between the weights of equal volumes, or between the...

...hydrogen combine with one volume of oxygen, etc. In order to explain this discovery Avogadro assumed that equal volumes of different gases, at the same...and pressure, contain the same number of molecules, a statement which is often expressed otherwise by saying that the densities of gases are proportional...

...value for all. But what shall this volume be ? The hypothesis of Avogadro is that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. The masses of equal volumes are therefore proportional to the molecular weights. The particular volume...

...overcome by a hypothesis, which AVOGADRO enunciated in 1S11, to the effect that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. AVOGADRO further supposes that the molecules of oxygen, hydrogen, chlorine, and other elements consist...

...a fundamental generalisation first made in the beginning of the last century. Equal volumes of all gases at the same temperature and pressure contain the same number of molecules. In this form it has been known successively as Avogadro's rule, Avogadro's hypothesis, and, lastly,...
