The composition of a sample of Wustite is `Fe_(0.93)O_(1.00)`. What percentage of the iron is present in the form of `Fe (III)`?

A

`15%`

B

`25%`

C

`35%`

D

`45%`

Text Solution

Verified by Experts

The correct Answer is:
A
The total charge of `Fe^(2+)` and `Fe^(3+)` should be 2.
Let , the percentage of `Fe^(3+)=x`
Hence, `3xx x + 2(0.93-x)=2`
`therefore x = 0.14`
% of `Fe^(3+)=(0.14)/(0.93)xx100=15%`
Hence, (A) is the correct answer.
