Atomic mass refers to the weight of the nucleus, which is roughly 1,800 times greater than that of the electrons. Tocalculate atomic mass, you simply add the number of protons and neutrons. Carbon atoms, for example, possess six protons and six neutrons, giving them an atomic mass of 12....

Calculating the Molar Mass of an Element By simply using the atomic mass of the given element and then multiplying it by the conversion factor grams per mole, you can easily figure out the molar mass of any element. You should find the relative atomic mass of the given element. This type...
Atomic Mass Atoms are so small, it is difficult to discuss how much they weigh in grams. Use atomic mass units. an atomic mass unit (amu) isCH O® CO HO
The isotopic mass is referred as mass of the most abundant isotope of an element. The relative isotopic mass of an isotope mass of one atom of the isotope = 12 x mass of one atom of 12C
