Karlsruhe international chemical conference

One of the key components of such a scheme was provided in I860 by the Italian chemist Stanislao Cannizzaro, who announced at an international chemical conference in Karlsruhe that the work of his compatriot Amedeo Avogadro provided an improved list of the atomic weights of the elements. This list allowed an accurate ranking of the elements by weight, from the lightest (hydrogen) to the heaviest. 

But her instincts had been correct Mendeleev was worth the effort. He continued at the University of St. Petersburg, writing a dissertation that won him a traveling fellowship. While in Europe on this fellowship, he, like Lothar Meyer, attended the Karlsruhe Conference, the first international chemical conference, which was held to resolve difficulties with definitions of atoms, atomic weights, and nomenclature. The conference was not particularly productive, but on the way out the door, Mendeleev was handed a pamphlet by Cannizzaro, explaining the hypothesis of Avogadro. He read it, and it made sense.

Mendeleev also attended the 1860 Karlsruhe Congress, the first international chemistry conference. Many of the leading chemists of the day were in attendance, and one of the central questions addressed was the appropriate method for calculating atomic weight. Different chemists used different systems, leading to widespread confusion over everything from nomenclature to chemical formulas. Mendeleev heard the Itafian chemist Stanislao Cannizzaro present Amedeo Avogadro s hypothesis that equal vol-tunes of gas under equal temperature and pressure contained equal numbers of molecules.
