The formula for aluminum chromate is Al2(CrO4)3, so there are 12 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
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.)
Aluminum oxide has a chemical formula of Al2O3, which means there are 2 aluminum atoms and 3 oxygen atoms in each molecule of aluminum oxide.
The reactant aluminum phosphate has a chemical formula AlPO4. There are 4 oxygen atoms in one molecule of aluminum phosphate.
There are 12 oxygen atoms in a molecule of aluminum sulfate. The formula for aluminum sulfate is Al2(SO4)3. This tells us there are 3 sulfate ions, each with 4 oxygen atoms per sulfate, so 3 * 4 = 12.== ==
Aluminum permanganate has the chemical formula Al(MnO4)3. This means there are a total of 8 atoms in one molecule of aluminum permanganate - 1 aluminum atom, and 3 manganese and 12 oxygen atoms from the permanganate group.
There are a total of 17 atoms in one molecule of silver chromate (Ag2CrO4). This includes 2 silver atoms, 1 chromium atom, 4 oxygen atoms, totaling 7 atoms for each repeating unit in the compound.
2 Al and 3 O
there are four.
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.
Aluminum oxide has a chemical formula of Al2O3, which means there are 2 aluminum atoms and 3 oxygen atoms in each molecule of aluminum oxide.
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.)
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
The reactant aluminum phosphate has a chemical formula AlPO4. There are 4 oxygen atoms in one molecule of aluminum phosphate.
There are three oxygen atoms present in a formula unit of Aluminum Hydroxide (Al(OH)3).
There are 12 oxygen atoms in a molecule of aluminum sulfate. The formula for aluminum sulfate is Al2(SO4)3. This tells us there are 3 sulfate ions, each with 4 oxygen atoms per sulfate, so 3 * 4 = 12.== ==
Al(OH)3 One atom of aluminum. Three atoms of oxygen. Three atoms of hydrogen.
Aluminum dichromate has the formula unit of Al2(Cr2O7)3. This means there are two aluminum, six chromate and 21 oxygen atoms present for a total of 29 atoms.
