13 h 56 min, 1 sept. 1860 ans - A group of chemists assembled at the First International Congress of Chemists in Karlsruhe, Germany to settle the issue of atomic mass as well as some other matters that were making communication difficult. Stainslao Cannizzaro presented a convincing method for accurately measuring the relative masses of atoms. His method enabled chemists to agree on standard values for atomic mass and initiated a search for relationships between atomic mass and other properties of the elements.
