    50 ml of 1 M oxalic acid is shaken with 0.5 g of wood charcoal. The final concentration of the solution after adsorption is 0.5 M. Amount of oxalic acid absorbed per gram of charcoal is

    A) 3.45 g              

    B) 3.15 g

    C) 6.30 g              

    D) None

    Correct Answer: C

    Solution :

    \[W=\frac{126\times 1\times 50}{1000}\,\,\Rightarrow \,\,6.3\] (Molecular weight of oxalic acid \[\to \] 163) \[0.5\,g\,\to \,\frac{6.3}{2}\] \[1\,g\,\,\to \,\,\frac{6.3}{2\times 0.5}\,\,\times 1\,\,\,\Rightarrow \,\,\,6.3\,\,g\]
