define relative isotopic mass

mass compared with 1/12th mass of carbon-12

• based the mass of a carbon atom with atomic number 12, the standard for atomic masses

define relative atomic mass

weighted mean mass compared with 1/12th mass of carbon-12

• based the mass of a carbon atom with atomic number 12, the standard for atomic masses

how is mass spectrometry used

• the determination of relative isotopic masses and relative abundances of the isotope

• calculation of the relative atomic mass of an element from the relative abundances of its isotopes
