NH2 (a) In pervoksite structure bivalent cations are present in primitive cubic lattice and tetravalent cation is present at body centre and anions are in face centre. If atoms are removed from one of the face diagonals then two Mg2+ ions from two corners and one 0 2 ~ ion from face centred will be removed. 1 3 Effective number of Mg2+ = — x 6 = — [1] 8 4 71 Effective number of O = — x 5 = 5/2 [1] 2 +4 Effective number of Ti =1 [1] 3 5 mass of unit cell = — x 24 + — x 16 + 1 x 48 [1] 4 4 Molar mass .-. density of unit cell = Molar volume 106 6.023 x 10 23 x (2 x 0.72 x10' 8 ) 3 _ 106 23 6.023 x10 x 2.986 x10~24 = 58.94 gm/cc
