`A_(3),B_(2)` is a sparingly soluble salt of molar mass M `(g mol^(-1)` and solubility x g `L^(-1)` The solubility product satisfies `K_(sp)=a(x)/(M)^(5)` . The value of a is__________(Integer answer)

Text Solution

Verified by Experts

The correct Answer is:
`108`
`A_(3)B_(2)(s)hArrunderset(3s)(3A_((aq))^(+2))+underset(2s)(2B_((aq))^(-3))`
`K_(SP)=(3s)^(3)(2s)^(2)`
`K_(SP)=108S^(5)` and `s=(x//M)`
`K_(SP)=108((x)/(m))^(5)`
given `K_(SP)=a((x)/(m))^(5)`
comparing `a=108`.
