The chemical formula for scandium sulfide is Sc2S3. Therefore, in one molecule of scandium sulfide, there are 2 scandium atoms and 3 sulfur atoms, totaling 5 atoms.
Scandium hydroxide has one scandium atom (Sc), three oxygen atoms (O) and three hydrogen atoms (H) per formula unit. Therefore, there are a total of seven atoms in one molecule of scandium hydroxide.
Tetra sulfide usually refers to a compound containing four sulfur atoms. Therefore, in a molecule of tetra sulfide, there are four sulfur atoms.
To find the number of atoms in a sample of scandium, you need to first calculate the number of moles using the molar mass of scandium (44.96 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. 341g of scandium is approximately 7.58 moles, which corresponds to 4.57 x 10^24 atoms.
In one molecule of cadmium sulfide (CdS), there are one cadmium atom and one sulfur atom.
There are 3.24 x 10^24 hydrogen atoms in 2.70 moles of ammonium sulfide. This is calculated by multiplying the number of moles of ammonium sulfide by the number of hydrogen atoms in one molecule of ammonium sulfide (4).
