A) \[143.5\times {{10}^{-5}}\]
B) \[143.5\times {{10}^{-2}}\]
C) \[14.35\times {{10}^{-1}}\]
D) \[1.435\times {{10}^{-6}}\]
Correct Answer: A
Solution :
\[{{K}_{sp}}={{10}^{-10}}\] \[s=\sqrt{{{K}_{sp}}}=\sqrt{{{10}^{-10}}}=1\times {{10}^{-5}}\,\text{mole/litre}\] \[=1\times {{10}^{-5}}\times 143.5\,\text{g/litre}\] \[=143.5\times {{10}^{-5}}\,\text{g/litre}\]
