There are a total of 11 atoms present in one molecule of calcium bicarbonate (Ca(HCO3)2). This includes 1 atom of calcium (Ca), 2 atoms of hydrogen (H), 2 atoms of carbon (C), and 6 atoms of oxygen (O).
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
In 3Ca(OH)2 there are three Ca(OH)2 - (Calcium hydroxide) moleculesIn one Ca(OH)2 there is one Calcium, and two (OH) units. In one (OH) unit there is one Oxygen and one Hydrogen. With the above information it evident that there are 5 atoms in one Ca(OH)2 molecule and as there are 3 of these molecules present, there would be a total of 15 atoms present in 3Ca(OH)2

There are three calcium (Ca) atoms in the compound Ca(NO3)2.
The atomicity of a compound indicates how many atoms are present in a single molecule of the compound. In the case of calcium hydroxide (Ca(OH)2), the atomicity is 4 (1 calcium atom + 2 oxygen atoms + 2 hydrogen atoms). This calculation considers the total number of different atoms present in the molecule.
In 3 formula units of Ca(NO3)2, there are a total of 9 calcium (Ca) atoms, 6 nitrogen (N) atoms, and 18 oxygen (O) atoms, giving a total of 33 atoms.
There is 1 Ca atom in calcium hydroxide. The formula is Ca(OH)2
