Analysis shows that an oxide ore of nickel has formula Ni_0.98O_1.00. The percentage of nickel as Ni³⁺ ions is nearly

In orthorhombic, the value of a, b and c are respectively 4.2, 8.6 and8.3. given the molecular mass of the solute is 155 g mol^-1 and that of density is 3.3 g/cc, the number of formula units per unit cell is

A solid has a structure in which ‘W’ atoms are located at the corner of a cubic lattice ‘O’ atoms at the centre of edge and Na atoms at the centre of the cube. The formula for the compound is

Ferrous oxide has a cubic structure and each edge of the unit cell is 5.0. Assuming density of the oxide as 4.0 g/cm^-3, then the number of Fe²⁺ and O^2- ions present in each unit cell will be

In a solid ‘AB’ having the NaCl structure, ‘A’ atoms occupy the corners of the cubic unit cell. If all the face – centred atoms along one of the axes are removed thye the resultant stoichiometry of the solid is
