There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the Periodic Table. e.g. Ca 20 40.078
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
Calcium nitrate has 9 atoms.
1.34 moles Ca x 6.02x10^23 atoms Ca/mole Ca = 8.07x10^23 atoms of Ca
3 - calcium2 - phosphorus8 - oxygenTotal atoms, 13.

For plutonium 239: ca. 74,68.1023 atoms
Calcium nitrate has 9 atoms.
There is 1 Ca atom in calcium hydroxide. The formula is Ca(OH)2
Calcium hypochlorite - Ca(ClO)2 has 5 atoms.
1.34 moles Ca x 6.02x10^23 atoms Ca/mole Ca = 8.07x10^23 atoms of Ca
3 x 6.02E23 molecules.
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).
3 - calcium2 - phosphorus8 - oxygenTotal atoms, 13.
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.
