Explain the difference between these things, or else admit you know nothing about what you're talking about.
This is complete nonsense. All readers are advised to ignore anything Dwayne has to say about chemistry from this point onwards.
Well, simply James R.
The in the time frame of Avogadro the means of makeing observation and definition in chemistry are not the same as your current assement and ability to make measurement. Just as in the time of Evanglista Torricelli and the first invention of the barometer. The Neutron was discovered by Sir James Chadwick in 1932. Avogadro had no conception of the neutron.
Clearly your disagreance, suggest that you believe that Avogadro had prior knowledge of the existance of the neutron.
Their are 3 types of hydrogen which do you think he had contact with, if you assume that he had H1 then his determination in comparison to every other element would be wrong, the only choice amoungest the hydorgen family of isotopes is H2.
In the last effort to understand his assement,where there is some other option, Avogadro would have to have been working with molecular hydrogen in stead of H2 to gain a comparison to every other atomic element.
it is up to you to figure that out, even so because Avogadro did not know of the neutron he could not make the relavant assement to the molecular gram any other way than to count the hydrogen as one atom, and each other atomic element a group mulitude of the prime atom Hydrogen.
The same exsit for measurements with gases, each molecule although a atomic element, contains so many atoms (prime hydrogen). so then two different gases take from the same room and filled in a container have a relative number of atoms but different atomic weights.
The AMU gram takes into account the mass of the neutron.
James R your supposed to be a moderator of the Physics you should have already understood what i said, may be you have been spending to much time with ULTRA who seems to claim that he is some chemistry wiz director of some chemical company ect.. but he can not determine the cycle of nuclear reactions. nor has post no such solution to the problem in japan with the Nuclear Plant.
