The composition of a sample of Wustite is `Fe_(0.93)O_(1.00)`. What fraction of iron is present in the from of `Fe^(2+)` ion ?

A

I, II & III

B

I & II

C

I & III

D

II & III

Text Solution

Verified by Experts

The correct Answer is:
D
Let no. of `Fe^(2+) = x`
no. of `Fe^(2+) = 0.93 - x`
then `2x + 3 (0.93 - x) = 2`
`x = 0.79`
