Aluminum sulfide is Al2S3, which has 3 sulfur atoms per formula unit. 1.10mol means 1.10(6.02x1023), which is 6.62x1023 formula units. Multiple that by 3 to get your sulfur atoms: 6.62x1023(3) = 1.99x1024 sulfur atoms.
If you think to allotrope tetrasulfur: 4 atoms.

Cadmium sulfide (CdS) has two atoms.
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
The chemical formula for gold sulfide is Au₂S. This means that one molecule of gold sulfide contains 2 gold atoms and 1 sulfur atom, for a total of 3 atoms.
For aluminum sulfide (Al2S3), the ratio of aluminum to sulfur atoms is 2:3. This means that for every 3 atoms of sulfur, 2 atoms of aluminum will react. So, to produce aluminum sulfide from 1.33 x 10^24 atoms of sulfur, you would need (2/3) * 1.33 x 10^24 atoms of aluminum, which is approximately 8.87 x 10^23 atoms of aluminum.

Hydrogen Sulfide has a total of three atoms. Hydrogen has two, and Sulfur has one. H2S.
Answer
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.
Hydrogen sulfide (H2S) contains 2 elements: hydrogen and sulfur. It consists of 2 hydrogen atoms and 1 sulfur atom.
