- 1Relative Isotopic Mass (RIM)mass of one atom of the isotope
_______________
1/12 the mass of a C-12 atom - 2Isotopes of C-12 was chosen as standard because1) C-12 is abundant in nature.
2) It can be easily identified in a mass spectrometer.
3) easy to handle since it exists as a solid at r.t. and pressure. - 3Relative atomic mass (Ar)average mass of an atom of the element
______________
1/12 the mass of a C-12 atom - 4Relative molecular mass (Mr)average mass of 1 molecule of the element/compound
_________________
1/12 of mass of one C-12 atom - 5Relative formula mass (RFM)mass of 1 formula of ionic compound
_____________________
1/2 of mass of 1 atom of C-12
