![]() ![]() Its abundance in the solar system is 10 parts per million, by weight. Please let us know how we can improve this web app. Mn is the 12th most abundant element in the Earth’s crust, accounting for 0.1 of its weight (360 parts per million). Related: Molecular weights of amino acids Weights of atoms and isotopes are from NIST article. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. Manganese is a monoisotopic element and its atomic weight is determined solely by its isotope 55 Mn. Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygens is 16. (Show more) atomic weight, also called relative atomic mass, ratio of the average mass of a chemical element ’s atoms to some standard. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Atomic mass (Da) Isotopic abundance (amount fraction) 55 Mn.
