FAQ

What is the molar mass of Hg?

M(Hg) = 200.59 g/mol

How is the molar mass of mercury different from its atomic weight?

Only in units: the relative atomic mass Ar(Hg) = 200.59 has no unit, and the molar mass M(Hg) = 200.59 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Hg?

m = n × M = 2 mol × 200.59 g/mol = 401.18 g.
