Nov 21, 2020 · Atomic mass of Copper is 63.546 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.

The atomic mass is usually found on the periodic table and is given in atomic mass units (amu). Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound. Add them together: add the results from step 3 to get the total molar mass of the compound. Example: calculating ...

Copper (29 Cu) has two stable isotopes, 63 Cu and 65 Cu, along with 28 radioisotopes. The most stable radioisotope is 67 Cu with a half-life of 61.83 hours. Most of the others have half-lives under a minute.

原子质量单位（amu或u）有时称统一原子质量单位，或 道尔顿 （Dalton，Da，D）是用来衡量原子或分子质量的单位，它被定义为碳12原子质量的1/12。 1 u = 1/NA 克 = 1/ (1000 NA) 千克 (NA为 阿伏伽德罗常数) =1.66053886×10^-27 kg ; “amu”这个符号一般出现在较老的文献中。 在书写原子量的时候经常不写任何单位，而将原子质量单位作为默认的单位。 在生物化学和分子生物学文献中（特别是描述蛋白质的时候），一般使用道尔顿这个名词，或者使用Da。 由于蛋白是 大分 …

The atomic weight is the mass of an atom, typically expressed in atomic mass units (amu). For an isotope, it is the mass of the nucleus, that is the mass of the protons and neutrons, as the mass of the electrons are considered negligible.

No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu. Why 12.01 amu? If a sample of carbon was placed in a mass spectrometer the spectrometer would detect two different C atoms, 12 C and 13 C.
