To work this out you need to know the atomic weight of calcium and Avogadros number, which is the number of atoms in a gram atom.
Calcium has an atomic weight of 40.078. Therefore a gram ato is 40.078 grams which contains 6.02214129(27)×1023 atoms.
1g of calcium contains 6.02214129(27)×1023 / 40.078
1.502 X 1022
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Calcium carbonate is CaCO3 and has 5 atoms. One calcium (Ca), one carbon (C) and three oxygen (O) atoms
Calcium nitrate has 9 atoms.
There are approximately 6.022 x 10^23 sulfur atoms in one gram of sulfur, according to Avogadro's number which represents one mole of atoms.
Calcium iodide (CaI2) has two iodine atoms and one calcium atom.
In one molecule of CaF2, there is one calcium atom and two fluorine atoms.
There are 5 atoms in one formula unit of calcium chloride (CaCl2): one calcium (Ca) atom and two chloride (Cl) atoms.
one molecule of calcium carbonate (ca co3) contains 5 atoms.
There are five atoms in the formula of calcium carbonate: one calcium atom (Ca), one carbon atom (C), and three oxygen atoms (O).

In 50 grams of calcium carbonate, there are approximately 6.02 x 10^23 atoms. This is because one mole of any substance contains Avogadro's number of particles, which is 6.02 x 10^23 atoms for elements or molecules.
Calcium oxide has the chemical formula CaO, which consists of one calcium atom and one oxygen atom. So, there are a total of 2 atoms in calcium oxide.
Calcium oxide (CaO) contain one atom of calcium.
Calcium Carbonate (CaCo3) has one calcium (Ca) atom, one carbon (C) atom and three oxygen (O3) atoms.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Calcium carbonate is CaCO3 and has 5 atoms. One calcium (Ca), one carbon (C) and three oxygen (O) atoms
