Question

$\mathrm{M}_3 \mathrm{~A}_2$ is a sparingly soluble salt of molar mass $y \mathrm{~g} \mathrm{~mol}^{-1}$ and solubility $x \mathrm{~g} \mathrm{~L}^{-1}$. The ratio of the molar concentration of the anion $\left(\mathrm{A}^{3-}\right)$ to the solubility product of the salt is

Select the correct option:

A

$\frac{1}{54} \cdot \frac{y^4}{x^4}$

B

$\frac{y^5}{108 x^4}$

C

$108 \cdot \frac{x^5}{y^5}$

D

$\frac{1}{108} \frac{y^4}{x^4}$

✓ Correct! Well done.
