3 Ni(OH)2 contain six oxygen atoms.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
Oxygen is a gas composed of oxygen molecules. A stable oxygen molecule is made from two oxygen atoms, represented as O2.
Oxygen is an element in its own right, so it only contains one element: oxygen.
To determine the number of oxygen (O) atoms in a formula, you need to specify the compound or molecule in question. Once you provide the formula, I can help you calculate the number of oxygen atoms present.
In the formula 3Ni(OH)₂, each hydroxide (OH) group contains one oxygen atom. Since there are two hydroxide groups per nickel hydroxide unit and three units in total, the total number of oxygen atoms is 3 units × 2 oxygen atoms/unit = 6 oxygen atoms. Therefore, the formula 3Ni(OH)₂ represents 6 atoms of oxygen.
One molecule of barite, which is BaSO4, contains one atom of sulfur and four atoms of oxygen.
There are 11 atoms in Al2O3: 2 aluminum atoms, abbreviated as Al, and 3 oxygen atoms, represented as O.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
Oxygen is a gas composed of oxygen molecules. A stable oxygen molecule is made from two oxygen atoms, represented as O2.
In 2H2O, there are 4 hydrogen atoms (2 from each H2 molecule) and 2 oxygen atoms.
In the graphic provided, there are a total of five hydrogen bonds explicitly represented between the hydrogen atoms and either nitrogen or oxygen atoms.
1 molecule of Calcium Carbonate -CaCO3, contains 3 oxygen atoms.
Nitrogen has 1 atom in a molecule, represented by the chemical symbol N. Oxygen typically exists as O2, with 2 oxygen atoms bonded together.
The formula CaCO3 represents 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
There are 4 oxygen atoms present in a formula unit of potassium sulfate, represented as K2SO4.

If you mean this Al2(CO3)3, then 9 oxygen atoms are represented.
