To determine the number of atoms in 4Al2O3, we first need to calculate the molar mass of Al2O3. Aluminum has a molar mass of 26.98 g/mol, oxygen has a molar mass of 16.00 g/mol. Therefore, the molar mass of Al2O3 is (226.98) + (316.00) = 101.96 g/mol.
Next, we convert 4 moles of Al2O3 to grams: 4 moles * 101.96 g/mol = 407.84 grams.
Finally, we use Avogadro's number to find the number of atoms: 407.84 grams / 101.96 g/mol * 6.022 x 10^23 atoms/mol = 2.42 x 10^24 atoms of aluminum and oxygen in 4Al2O3.

How many atoms of aluminum sulfur and oxygen are in 3 molecules of aluminum sulfate?
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.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.

How many oxygen atoms are in aluminum chromate?
In aluminum chromate, the chemical formula is Al2(CrO4)3. This means that there are a total of 12 oxygen atoms in aluminum chromate (4 oxygen atoms in chromiumate ion multiplied by 3 chromiumate ions).
When aluminum combines with oxygen three oxygen atoms combine with this many aluminum atoms?
There are 13 protons in aluminum and 13 electrons. So, there are 13 atoms in aluminum. In oxygen, there are 8 protons and 8 electrons. thus there are 8 atoms. EDIT: This answer is absolutely and completely incorrect. (Dr.J.)
What is empirical formula of aluminum oxide?
The empirical formula of aluminum oxide is Al2O3, which indicates that each aluminum atom is bonded to two oxygen atoms. This ratio of aluminum to oxygen atoms is the simplest whole number ratio in which they combine.
How many atoms of oxygen are contained in 47.6g of aluminum carbonate?
There are 4 oxygen atoms in one molecule of aluminum carbonate (Al2(CO3)3). To find the number of moles of aluminum carbonate in 47.6g, we divide by its molar mass, 233.99 g/mol. Then, multiply by 4 to find the number of oxygen atoms.

How atoms does Al(OH)3?
Al(OH)₃, or aluminum hydroxide, consists of one aluminum atom (Al), three oxygen atoms (O), and three hydrogen atoms (H). Therefore, the total number of atoms in Al(OH)₃ is seven: 1 aluminum + 3 oxygen + 3 hydrogen = 7 atoms.

What is the oxidation number of Al in Al2o3?
In aluminum oxide (Al₂O₃), the oxidation number of aluminum (Al) is +3. This is determined by considering that oxygen typically has an oxidation number of -2. Since there are three oxygen atoms contributing a total of -6, the two aluminum atoms must have a combined oxidation number of +6, leading to an individual oxidation state of +3 for each aluminum atom.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
