Chemistry How many Fluorine ions are there in 202 grams of CaF2
HINT: Find the percentage of Fluorine in Calcium Fluoride, then find out how many grams of fluorine are in 200 grams of Calcium Fluoride. Lastly solve for ions

There are 48.72 g  Fluorine ions

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⁻) :
