FAQ

What is the molar mass of Au?

M(Au) = 196.97 g/mol

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

Only in units: the relative atomic mass Ar(Au) = 196.97 has no unit, and the molar mass M(Au) = 196.97 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Au?

m = n × M = 2 mol × 196.97 g/mol = 393.94 g.
