there are 3 in tottal
4 carbon 16 hydrogen
two atoms of hydrogen one atom of Sulfur and four atoms of oxygen
3 CaCl2 has 3 calcium atoms and 6 oxygen atoms.
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.
