The well known mineral fluorite is chemically clacium fluoride. Its is known that in one unit cell of this mineral there are 4 Ca^(2+) ions and 8 F^- ions and that of 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 hte unit cell is 5.46xx10^-8 cm in length. the density of the solid is 3.18 gcm^-3 . use this information to calculate the Avagadro's number. (Molar mass of CaF_2=70.08 g mol^-1 ).
