JEE Advanced 2024 — Paper 2 — Question 26

In a metal deficient oxide sample, (M and Y are metals), M is present in both +2 and +3 oxidation states and $\mathbf{Y}$ is in +3 oxidation state. If the fraction of $\mathbf{M}^{2+}$ ions present in $\mathbf{M}$ is $\frac{1}{3}$ , the value of $X$ is $\qquad$

Option A:
0.25
Option B:
0.33
Option C:
0.67
Option D:
0.75
Correct

Answer: D

Step-by-step solution

$\mathbf{M}_{\mathbf{x}} \mathbf{V}, \mathrm{n}_{\boldsymbol{a}}$ $+2 \times \frac{x}{3}+3 \times \frac{2 x}{3}=+2$ $x=0.75$
