determination of the relative atomic mass of an element using mass spectrometry (details of instrument not required)
Summary Notes
Summary Notes
Relative Atomic Mass (RAM or Ar) is the mass of each atom compared to Carbon (12). E.g. Magnesium has a mass of 24 which is twice as heavy as Carbon.
It is found through calculations involving the abundances of an elements’ Relative Isotopic Masses (see picture right).
Relative Molecular Mass is the atomic masses of each atom in a molecule added up e.g. CO2’s atomic mass is 12 + 16 + 16 = 44
