- Atomic Masses
- Relative Isotopic mass
- The mass of an atom of an isotope compared with one-twelfth of the mass of an atom of carbon-12.
- Oxygen = 16
- Hydrogen = 1
- Relative atomic mass
- The weighted mean mass of an atom of an element compared with one-twelfth of the mass of an atom of carbon-12
- Hydrogen = 1
- Fluorine = 19
- Relative molecular mass
- The weighted mean mass of a molecule compared with one-twelfth of the mass of an atom of carbon-12
- H20 ---> H=1 O=16 1+1+16=18
- Cl2 ---> 35.3 x 2 = 71
- Relative formula mass
- The weighted mean mass of a formula unit compared with one-twelfth of the mass of an atom of carbon-12
- CaBr2 --> 40.1 + (79.9 x 2) = 199.9
- Na3Po4 --> (23 x 3) + 31 + (16 x 4) = 164
- Relative Isotopic mass
