In 4CaCO3, there are a total of 4 calcium (Ca) atoms, 4 carbon (C) atoms, and 12 oxygen (O) atoms.
To determine the number of atoms in 4CaCo3, we first need to break down the formula. CaCo3 represents one calcium atom (Ca), one carbon atom (C), and three oxygen atoms (O). Therefore, 4CaCo3 would contain 4 calcium atoms, 4 carbon atoms, and 12 oxygen atoms. In total, there would be 20 atoms in 4CaCo3.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
There are 4 calcium atoms, 8 chlorine atoms, and 2 carbon atoms in 4CaCl2 (calcium chloride).
There are 9 nitrogen atoms, 3 phosphorus atoms, 12 hydrogen atoms, and 4 oxygen atoms in (NH4)3PO4.
