• D. 183.84

Answer: (C)

Verified step by step guidance

1. Understand that the atomic mass of an element is the weighted average mass of all the naturally occurring isotopes of that element, measured in atomic mass units (amu).
2. Recognize that the atomic mass is a characteristic property of each element and can be found on the periodic table.
3. Locate mercury (Hg) on the periodic table to find its atomic mass value, which is usually displayed below the element symbol.
4. Note that the atomic mass is not simply an average of the given numbers but is based on isotopic abundances and their masses.
5. Compare the given options to the known atomic mass of mercury from the periodic table to identify the correct value.
