<h3>Further explanation </h3>Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
%F in CaF₂ :
mass of Fluorine :
So mass Fluorine ions(2 ions F in CaF₂⇒Ca²⁺+2F⁻) :
