A) \[{{10}^{-3}}M\]
B) \[{{10}^{-4}}M\]
C) \[{{4}^{1/3}}\times {{10}^{-3}}M\]
D) \[2\times {{10}^{-5}}M\]
Correct Answer: A
Solution :
\[{{A}_{2}}B\,2{{\underset{2S}{\mathop{A}}\,}^{+}}+B_{S}^{2-}\] \[{{(2S)}^{2}}S=4\times {{10}^{-9}}\] \[\Rightarrow \,\,S={{10}^{-3}}\] moles/It.You need to login to perform this action.
