Mineral calcium fluoride has \( 4 \mathrm{Ca}^{+2} \) ion and \( 8 \mathrm{~F}^{-} \)ions in one unit cell. \( \mathrm{All}_{\mathrm{Ca}^{+2}} \) are arranged in fcc lattice
\( \mathrm{P} \) and \( F^{-} \)ions fill all tetrahedral voids. The edge of unit cell is \( 5.46 \times 10^{-8} \mathrm{~cm} \). Density of solid is

W \( 3.18 \mathrm{~g} / \mathrm{cm}^{3} \). Calculate the value of Avogadro's number If molar mass of \( \mathrm{CaF}_{2}=78 \mathrm{~g} / \mathrm{mol} \).
