SOLVED:A Calcium fluoride is the well-known mineral fluorite. Each unit cell contains four Ca^2 ions and eight F^- ions. The F - ions fill all the tetrahedral holes in a face centered cubic lattice of Ca^2 ions. The edge of the CaF2 unit cell is 5.46295 ×10^-8 cm in length. The density of the solid is 3.1805 g / cm^3 . Use this information to calculate Avogadro's number.

Solid calcium fluoride (CaF, 2 ) reacts with sulfuric acid to form solid calcium sulfate and gaseous hydrogen fluoride (HF). The HF is then dissolved in water to form hydrofluoric acid. A source of calcium fluoride is fluorite ore containing 96.0 wt % CaF2 and 4.0 % SiO2 In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wt% aqueous sulfuric acid, supplied 15% in excess of the stoichiometric amount. Ninety-five percent of the ore dissolves in the acid. Some of
