Atomic mass of Hg: 200.1 grams
65.0 grams × (6.02 × 1023 atoms) / (200.1 grams) = 2.00 × 1023 atoms Hg
1mole of Mercury weights 201grams.
1mole = 6.02 x 10^23 number of atoms.
So 1atom weights = 201/(6.02 x 10^23)g = 33.38 x 10^(-23) grams
Since mercury is a metal it does not form molecules, but instead exists as individual atoms.
It is elemental. Mercury is made of mercury. Atoms of mercury are made of mercury atoms.
A complete answer would require specification of a temperature, but at 20C, mercury is reported to have a density of 13.5939 grams per milliliter, so that 1.80 mL would have a mass of 1.80 X 13.5939 or 245 grams, to the justified number of significant digits. The gram atomic mass, which is the mass of Avogadro's number of mercury atoms, is 200.6; and Avogadro's Number is about 6.022 X 1023. Therefore the number of atoms in the volume specified is (245/200.6)(6.022) X 1023 or 7.345 X 1021 atoms.
25,1 grams sulfur contain 4,7147765.10e23 atoms.
What is the mass, in grams, of 2 × 1012 atoms of potassium?
Atomic mass of Ag: 107.9 grams5.00 grams × (6.02 × 1023 atoms) / (107.9 grams) = 2.79 × 1022 atoms Ag
Density = mass/volume ( Mercury is 13.534 grams/milliliter, and milliliter = cubic centimeter ) 13.534 g/ml = grams/9.1 cc (or ml) = 123.1594 grams of Hg ( Mercury) 123.1594 grams Hg (1 mole Hg/200.6 grams)(6.022 X 10^23/1 mole Hg) = 3.7 X 10^23 atoms of mercury
It is elemental. Mercury is made of mercury. Atoms of mercury are made of mercury atoms.
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
Two mercury atoms present in mercury(II)chloride.

The number of mercury atoms is 11,74458.10e23.
Mercury(l) chloride
Helium because it has fewer atoms, so there are more atoms needed to have 3.5 grams of it.
370 grams of mercury is equal to 1,844 moles.
603 grams of mercury are equivalent to 3,006 moles.
25,1 grams sulfur contain 4,7147765.10e23 atoms.
