The molar solubility ( in mol `L^(-1))` of a sparingly soluble salt `MX_(4)` is `'s'`. The corresponding solubility product `K_(sp), 's'` is given in terms of `K_(sp)` by the relation

Answer

D

Explanation

`MX_(4) to M^(4+) + 4X^(-)`
s
s 4s
`K_(sp)=(s)(4s)^(4) = 256S^(5) implies s=(K_(sp)/256)^(1//5)`
