Mercury has an atomic weight of 200.59 amu (atomic mass unit). It has atomic number of 80 and a molecular weight of 200.59 and belong to the Group 12 (Zinc group, II b) of the periodic table 2. Mercury have boiling and melting points of 356.9 C and -38.87, respectively. And have the unique characteristic of being liquid at room temperature.

Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. Mercury is a silver-white dense metal with a mirror like appearance.

(1 u is equal to 1/12 the mass of one atom of carbon-12)

Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).
