The molar mass of mercury (Hg) is approximately 200.59 g/mol.
This value is derived from the atomic mass of mercury, which is listed in the periodic table. The molar mass indicates how much one mole of mercury weighs, and it is crucial in stoichiometric calculations in chemistry. It means that if you have one mole of mercury, it would weigh about 200.59 grams. Understanding the molar mass of elements like mercury helps in accurately measuring and reacting quantities in chemical reactions.
