Each molecule of Al2S3 is composed of one Al3+ ion. Since a mole is equal to 6.022 x 1023 molecules, there would be 6.022 x 1023 Al3+ ions in one mole of Al2S3.
The correct chemical equation for the reaction between aluminum metal and sulfur is: 2Al + 3S → Al2S3. This equation shows that two atoms of aluminum combine with three atoms of sulfur to form aluminum sulfide.
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
Two aluminum atoms and three sulfur atoms would have the formula Al2S3. When writing a formula for an ionic compound, the positive ion (in this case Al3+) is written first. Very often, an ionic compound is composed of a metal and a nonmetal, as in Al2S3, in which case the metal ion will be written first because it will always be positively charged.
The formula for the compound formed between aluminum and sulfur atoms is Al2S3. This is because aluminum typically forms a 3+ cation, while sulfur forms a 2- anion, resulting in a compound with a 2:3 ratio of aluminum to sulfur atoms.
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.

Calcium fluoride has the chemical formula CaF2, where there is one calcium atom and two fluorine atoms bonded together. Aluminum sulfide has the chemical formula Al2S3, where there are two aluminum atoms and three sulfur atoms bonded together.
2Al + 3S -> Al2S3
The chemical formula for the ionic compound formed from aluminum and sulfur is Al2S3. This compound is formed by the transfer of electrons between aluminum (Al) and sulfur (S) atoms, resulting in the formation of Al3+ and S2- ions which combine in a 2:3 ratio to create Al2S3.
When aluminum metal reacts with solid sulfur, the result is the formation of solid aluminum sulfide. This chemical reaction is a synthesis reaction where aluminum and sulfur combine to form a new compound, aluminum sulfide, with the formula Al2S3.
The chemical formula for a compound between Al and S is Al2S3. Aluminum typically forms a 3+ cation and sulfur typically forms a 2- anion. To balance the charges, you need two aluminum atoms for every three sulfur atoms.
