Let be the number of fluorine atoms in one formula unit of Fluorapatite, and be the number of fluori — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

The chemical formula of Fluorapatite is $3Ca_3(PO_4)_2 \cdot CaF_2$, which contains 2 fluorine atoms per formula unit ($X = 2$). Cryolite is $Na_3AlF_6$, containing 6 fluorine atoms per formula unit ($Y = 6$). Therefore, $X + Y = 8$.
