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.
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.
Cadmium sulfide (CdS) has two atoms.
Scandium sulfide ScS: 2 atomsScandium sulfide Sc2S3: 5 atoms
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
I am not sure of the work but, i know the answer is 8.9 X 10^23 atoms Al.
Answer
Hydrogen Sulfide has a total of three atoms. Hydrogen has two, and Sulfur has one. H2S.
Each molecule of hydrogen sulfide contains two hydrogen atoms and one sulfur atom.
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.
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 zinc floride is ZnF2. Thus, a single molecule of zinc floride contains one zinc atom and two floride atoms, for a total of three atoms.
Cadmium sulfide (CdS) has two atoms.

Two hydrogen atoms to form hydrogen sulphide (H2S) . It is the smell of rotten eggs.
There are 16 protons in the sulfide ion, which is similar to the sulfur atom.
Barium sulfide (BaS) has two atoms.
