A) \[2.46\times {{10}^{14}}\]
B) \[1.36\times {{10}^{-4}}\]
C) \[2.60\times {{10}^{-7}}\]
D) \[1.20\times {{10}^{-10}}\]
Correct Answer: B
Solution :
\[M{{X}_{2}}\]⇌ \[\underset{(S)\,\,\,}{\mathop{{{M}^{+}}}}\,+\underset{{{(2S)}^{2}}\,\,}{\mathop{2{{X}^{-}}}}\,\]; \[{{K}_{sp}}=4{{S}^{3}}\] \[S=\sqrt[3]{\frac{{{K}_{sp}}}{4}}=\sqrt[3]{\frac{1\times {{10}^{-11}}}{4}}=1.35\times {{10}^{-4}}\]
