How Many Atoms in Aluminum Sulfate
On the number of atoms in alum
alum, the chemical name is aluminum sulfate. To know the number of atoms in it, you need to study its chemical formula in detail. The chemical formula of aluminum sulfate is $Al ³ (SO)
Looking at this chemical formula, the number of aluminum atoms in the molecular aluminum sulfate can be seen from the number "2 dollars $" in the lower right corner of $Al $, which is a diatom. The number of sulfur atoms is in $SO $. Although there is no number in the lower right corner of "$S $", there is a number "3 dollars $" outside the brackets, so the number of sulfur atoms is 1 dollar × 3 = 3 $atoms. The number of oxygen atoms, the number of oxygen atoms in $SO $is 4 dollars $, multiplied by "3 dollars $" outside the brackets, that is, 4 dollars × 3 = 12 $atoms.
In summary, in the molecule aluminum sulfate, there are two aluminum atoms, three sulfur atoms, and twelve oxygen atoms. Then the total number of atoms in a molecule of aluminum sulfate is: 2 dollars + 3 + 12 = 17 $atoms.
Therefore, if you want to understand the number of atoms in a substance, you must study the mystery of the chemical formula to obtain its true meaning.
