As indicated by the subscript on the atomic symbol for oxygen, there are 3 oxygen 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.)
There are three atoms of oxygen per calcium carbonate molecule. name: chalk IUPAC name: calcium carbonate compound formula: CCaO3 formula: CaCO3 (This information was obtained from http://www.wolframalpha.com)
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).
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.
Al2(CO3)3..ie for every 3 CO3 u will have 2 aluminum . i.e 3 carbon 9 oxygen and 2 aluminum makes one aluminum carbonate.
The formula unit of calcium carbonate is CaCO3. Therefore, it has 3 oxygen atoms.
As indicated by the subscript on the atomic symbol for oxygen, there are 3 oxygen atoms.
1 molecule of Calcium Carbonate -CaCO3, contains 3 oxygen atoms.
There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
2 aluminum atoms 4 sulphur atoms 4 oxygen atoms
There is no oxygen in calcium carbonate. Calcium carbonate is composed of calcium, carbon, and oxygen atoms. The chemical formula for calcium carbonate is CaCO3, indicating that each molecule contains one calcium atom, one carbon atom, and three oxygen atoms.
There are a total of 12 oxygen atoms in two calcium carbonate formula units. Each formula unit of calcium carbonate (CaCO3) contains 3 oxygen atoms, so for two formula units, there would be 6 oxygen atoms in each unit, totaling 12 oxygen atoms.
6.213 grams Al2(CO3)3 (1mol Al2(CO3)3/233.99g)(9mol O/1mol Al2(CO)3)(6.022 X 10^23/1mol cpd.) = 1.439 X 10^23 atoms oxygen ( cpd means compound )
Two aluminum atoms and three oxygen 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.)
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.
