The formula unit of calcium carbonate is CaCO3. Therefore, it has 3 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 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)
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
1 molecule of Calcium Carbonate -CaCO3, contains 3 oxygen atoms.
Calcium carbonate is CaCO3 and has 5 atoms. One calcium (Ca), one carbon (C) and three oxygen (O) atoms
Calcium Carbonate (CaCO3)I mol CaCO3 contains 3 mol Oxygen atomsso 4.25 mol CaCO3 will have 12.75 mol Oxygen Atoms.
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
its CaCO3 so 1 calcium aton and 1 carbon atom with 3 oxygen atoms
Three molecules of calcium carbonate (CaCO3) has nine(9) oxygens. Think of 3CaCO3 = CaCO3 + CaCO3 + CaCO3. Each molecule of CaCO3 has ;- 1 atoms of calcium (Ca) 1 atom of carbon (C) 3 atoms of oxygen (O3 = O + O + O). So if one molecules of CaCO3 has 3 oxygens, then three molecules of CaCO3 has 3 x 3 = 9 oxygens. The answer!!!!!
The number 3 in the chemical formula CaCO3 indicates that there are three oxygen atoms in one molecule of calcium carbonate.
A molecule of CaCO3 contains 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
