The composition of a sample of Wustite is Fe _ 0.93 O . What is the percentage of iron present as Fe ³⁺ ?

Options

  1. A15 %
  2. B25 %
  3. C35 %
  4. D45 %

Correct answer

A. 15 %

Step-by-step solution

The total charge of Fe ²⁺ and Fe ³⁺ should be 2 . Let, the percentage of Fe ³⁺= x Hence, 3 x+2(0.93-x)=2 x=0.14 % of Fe ³⁺= 0.14 0.93 100=15 % Hence, (A) is the correct answer.
