Answer:
C.) One mole of mercury
Explanation:
You can determine which has the greatest mass by identifying each of their atomic masses. The atomic mass represents the mass of an element per 1 mole.
Gold (Au): 196.97 g/mol
Mercury (Hg): 200.59 g/mol
Barium (Ba): 137.33 g/mol
In this case, one mole of mercury has the greatest mass.
