Online chemistry calculator which helps you to find the relative atomic weight (Amu) of a chemical element. Calculator of Atomic Mass (Amu) of an Element Number of Neutron: Atomic Mass:Amu Formula of Atomic Mass: A = Number of protons + Number of neutrons ...
Here they do not want decimals, so we round this answer, giving us 157 amu as the average atomic mass of element R. Note: An average atomic mass will be a value closest to the isotope with the largest abundance. Since that was isotope 3 with an abundance of 0.7988 or 79.88%, we se...
The atomic mass or atomic weight of an element (or put it in simple term, mass of an atom) is found by addingnumber of neutronsand number of protons. In calculating the atomic mass of an atom, the number of electrons and daltons are usually ...
The standard atomic weight of an element, Ar°(E), is the “recommended value of atomic weight (relative atomic mass) of an element revised biennially by the CIAAW and applicable to elements in any normal material with a high level of confidence” [10]. It is comprised of either an inte...
