In 3CaCl2 there are 9(nine) atoms.
One molecule
CaCl2 contains
1 x calcium (Ca)
2 x chloine (Cl2)
Hence one molecule contains 3 atoms.
However, we have 3(three) molecules, indicated by the prefix '3'.
Hence 3 x 3 = 9 . So there are nine atoms in total present.
There is 1 atom of calcium in CaCl2. Each molecule of CaCl2 contains 1 calcium atom, 2 chlorine atoms, and a total of 3 atoms.
There are a total of 10 atoms in 2CaCl2. This is because each CaCl2 molecule contains 3 atoms: 1 calcium atom and 2 chlorine atoms. Multiplying by 2, there are 6 atoms in 2 CaCl2 molecules, and since there are 2 molecules, the total number of atoms is 10.
In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.
There are 5 atoms in one formula unit of calcium chloride (CaCl2): one calcium (Ca) atom and two chloride (Cl) atoms.
No, the oxidation number of CaCl2 is not 3. In CaCl2, calcium (Ca) has an oxidation state of +2, and each chlorine atom (Cl) has an oxidation state of -1. This combination allows for the compound to have a neutral charge.
There is 1 atom of calcium in CaCl2. Each molecule of CaCl2 contains 1 calcium atom, 2 chlorine atoms, and a total of 3 atoms.
Three.
There are a total of 10 atoms in 2CaCl2. This is because each CaCl2 molecule contains 3 atoms: 1 calcium atom and 2 chlorine atoms. Multiplying by 2, there are 6 atoms in 2 CaCl2 molecules, and since there are 2 molecules, the total number of atoms is 10.
There are two chlorine atoms in CaCl2.
There are three atoms in CaCl2 (calcium chloride) - one calcium atom and two chlorine atoms. It might be argued that there are ions inside the molecule instead of atoms. In that case there is one calcium ion and two chlorine ions.
In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.
Calcium chloride (CaCl2) consists of one calcium atom (Ca) and two chlorine atoms (Cl) in each molecule.
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
There are 5 atoms in one formula unit of calcium chloride (CaCl2): one calcium (Ca) atom and two chloride (Cl) atoms.

No, the oxidation number of CaCl2 is not 3. In CaCl2, calcium (Ca) has an oxidation state of +2, and each chlorine atom (Cl) has an oxidation state of -1. This combination allows for the compound to have a neutral charge.
There is no correct chemical formula described in your question. When calcium and chlorine combine, they form calcium chloride with a formula of CaCl2.
