Metal deficiency defect is shown by Fe 0 . 93 O . In the crystal, some Fe 2 + cations are missing and loss of positive charge is compensated by the presence of Fe 3 + ions. The percentage of Fe 2 + ions in the Fe 0 . 93 O crystals is____(Nearest integer)

Correct answer

0

Step-by-step solution

In Fe 0 . 93 O for every 93 Fe ions 14 are Fe + 3 and 93 - 14 = 79 are Fe + 2 ions ∴   % Fe + 2 = 79 93 × 100 = 84 . 9 % ∴ nearest integer = 85 %
