...C = 12, O = 16 and N = 14. In this connection it must be remembered that equal volumes of all yasrs at the same temperature and pressure contain the same number of molecules, hence the truth of the above statement. It will therefore be apparent that if we let N5, CO2 and CO...

...Dividing equation (i) by equation (2) we have f ni = f w2 or Ml = «2. That is, the equal volumes of all gases at the same temperature and pressure contain the same number of molecules. This is Avogadro's Hypothesis. Molecular Velocity. — Solving equation pV = | nww2 for u, we have...

...particles, and these in turn being made up of atoms. Avogadro's Hypothesis. — Equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules. Although Dalton's conception of an atom was an indivisible ultimate particle of matter, yet this term,...

...(Avogadro's) tegaiding the nature of gases, it is supposed that equal volumes of different yase# measured at the same temperature and pressure contain the same number of molecules or ultimate particles. The molecules are not the same thing as the atoms of an element; a molecule...

...this, and in many cases of dilute solution just twice as 'Avogadro's law is that equal volumes of all gases at the same temperature and pressure contain the same number of molecules and exert the same pressure, cf. Chapter I, p. 24. high as the theory calls for. Here was a fact that...

...generally used directly in terms of the densities of the gases since, as above stated, cqual volumes of the gases at the same temperature and pressure contain the same number of molecules. Use the equations 44 rI)a + 32 o, + 2? (co + W) W = , XC, (15) 12 (CO2 + CO) Where W — weight of...

...fundamental principles of chemistry. It may be stated concisely thus: Equal volumes of every gas or vapor at the same temperature and pressure contain the same number of molecules. Further reasons for accepting Avogadro's hypothesis will be given in the next chapter. Indeed, the...

...Kinetic Theory of gases, one must assume the statement generally known as the Hypothesis of Avogadro : " Equal volumes of different gases, at the same temperature...and pressure, contain the same number of molecules." This proposition Juis been adopted as a working hypothesis, and as such has stood the test of time....

...number of molecules in a given volume. The rate of movement is a function of the temperature. Hence equal volumes of different gases at the same temperature...and pressure contain the same number of molecules. f * T. Graham, Phil. Trans., 1861, vol. 157, p. 186. f The mean kinetic energy of the various kinds...

...chlorine to form 2 volumes of hydrochloric acid gas. The following conclusion is therefore justified: equal volumes of different gases at the same temperature and pressure contain either the same number of atoms or numbers of them in the different cases which stand to one another...
