The non stoichiometric compound Fe _ 0.94 O is formed when x % of Fe ²⁺ ions are replaced by as many 2 3 Fe ³⁺ ions, x is

Options

  1. A18
  2. B12
  3. C15
  4. D6

Correct answer

A. 18

Step-by-step solution

The number of Fe ³⁺ ions replacing x Fe ²⁺ ions = 2 x 3 vacancies of cations array l =x- 2 x 3 =x / 3 But x / 3=1-0.94=0.06, x=0.06 3 =0.18=18 % array
