...N2 be the numbers of the two kinds of molecules in unit volume before mixture, whence Nj = N2 or two different gases at the same temperature and pressure contain the same number of molecules per cc This is known as Avogadro's Law. a single gas and keep its density constant while altering its...

...0.09 0.488 1.316 0.134 Density of Gases. — Avogadro's law states the fact 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...

...likewise a constant and has the same value for all gases; or in other words that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. This statement, advanced as a hypothesis in 1811 by the Italian physicist Avogadro,6 is of great importance...

...vol. 2 vols. 3 H2 + N2 =2 H3N. 3 vols. 1 vol. 2 vols. 213. Avogadro's hypothesis. Equal volumes of all gases at the same temperature and pressure contain the same number of molecules. Or, in other words, all gaseous molecules under the same conditions occupy equal volumes of space....

...law" as it is usually called, may then be stated in the usual way as follows: equal volumes of all gases at the same temperature and pressure contain the same number of molecules. In the above examples we now say, in accordance with Avogadro's hypothesis, that one molecule of hydrogen...

...determining the relative heaviness of molecules by using Avogadro's law. Since equal volumes of all gases at the same temperature and pressure contain the same number of molecules, the weights of equal volumes of gases must bear the same ratio to one another as the weights of the...

...weights of gases are directly proportional to their molecular weights, because equal volumes of all gases at the same temperature and pressure contain the same number of molecules. Therefore, with gases analyzed volumetrically all that is necessary is to substitute the volumetric...

...molecules in the two quantities of gas must likewise be the same. In other words, equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules. This was first announced by an Italian physicist, Avogardo, in 1811, and is usually called Avogardro's...

...weight) of another. Here let us consider another interesting postulate called the law of Avogadro. All gases at the same temperature and pressure contain the same number of molecules within the same volume. More concretely stated, there are the same number of molecules in a cubic inch...
