An atomic mass unit is defined as precisely 1/12 the mass of an atom of carbon-12.
There are 48.72 g Fluorine ions
<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⁻) :

The correct answer is c. Temperature is the average kinetic energy of a sample so if two samples have the same temperature they will also have the same average kinetic energy. I hope this helps. Let me know if anything is unclear.
