The well known mineral fluorite is chemically calcium fluoride. It is well known that is one unit of this mineral, there are 4 Ca^(2+) ions and 8 F^- ions, and that Ca^(2+) ions are arranged in a fcc lattice. The F^- ions fill all the tetrahedral holes in the face-centred cubic lattice of Ca^(2+) ions. The edge of the unit cell is 5.46xx10^(-8) cm in length . The density of the solid is 3.18 "g cm"^(-3). Use this information to calculate Avogadro's number (Molar mass of CaF_2=78.08 "g mol"^(-1))

1.	The well known mineral fluorite is chemically calcium fluoride. It is well known that is one unit of this mineral, there are 4 Ca^(2+) ions and 8 F^- ions, and that Ca^(2+) ions are arranged in a fcc lattice. The F^- ions fill all the tetrahedral holes in the face-centred cubic lattice of Ca^(2+) ions. The edge of the unit cell is 5.46xx10^(-8) cm in length . The density of the solid is 3.18 "g cm"^(-3). Use this information to calculate Avogadro's number (Molar mass of CaF_2=78.08 "g mol"^(-1))
