A) \[5\times {{10}^{-13}}\]
B) \[25\times {{10}^{-10}}\]
C) \[1.25\times {{10}^{-13}}\]
D) \[5\times {{10}^{12}}\]
Correct Answer: A
Solution :
\[M{{X}_{2}}\] ⇌ \[\underset{(S)\,\,\,\,\,\,}{\mathop{{{M}^{2+}}}}\,+\,\underset{{{(2S)}^{2}}\,\,}{\mathop{2{{X}^{-}}}}\,\]; \[4{{S}^{3}}=4\times {{(0.5\times {{10}^{-4}})}^{3}}\] \[=5\times {{10}^{-13}}\]You need to login to perform this action.
