A) \[\frac{2}{309}\]
B) \[\frac{1}{412}\]
C) \[\frac{1}{103}\]
D) \[\frac{1}{206}\]
Correct Answer: B
Solution :
\[\underset{\begin{smallmatrix} (206g) \\ 2mol \end{smallmatrix}}{\mathop{2{{C}_{8}}{{H}_{7}}S{{O}_{3}}}}\,Na+\underset{1mol}{\mathop{C{{a}^{2+}}}}\,\xrightarrow[{}]{{}}\] \[1molC{{a}^{2+}}\] \[-2mol\,re\sin \] \[-412\,g\,re\sin \] Maximum \[C{{a}^{2+}}\] uptake\[=\frac{1mol}{412}/g\] of resin.
