The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. The melting point of Technetium is 2430 Kelvin (2157 ℃). • of a chemical compound, More information on If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Technetium was discovered in the year 1937 by Emilio Segrè and Carlo Perrier. 1) You may use almost everything for non-commercial and educational use. We use the most common isotopes. Additional troubleshooting resources. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Cloudflare Ray ID: 5f191e5b6cdbdcfe ›› More information on molar mass and molecular weight. There is an issue between Cloudflare's cache and your origin web server.
