What is the average atomic mass of Mg?Atomic Mass and Mass Number:The atomic mass is a form of calculated average mass for all the atoms of an element. This differs from mass numbers in that a mass number refers to the mass of a specific atom or the atoms of an isotope of an ...

For copper, should the atomic mass be represented as 63.546 g, 63.546 mg, or what? The answer is that atomic mass has no units at all. It is a relative number, showing how many times more massive the atoms of one element are compared to the atoms of the standard (carbon-12). ...

A pile of that number (one "mole") of Plutonium-239 would weigh exactly 239 grams. The point is, you can use this to convert between atomic mass units and grams. Basically you divide Avogadro constant by the atomic mass of the element to find the number of atoms of that element in ...
