    The amount of sugar \[({{C}_{12}}{{H}_{22}}{{O}_{11}})\] required to prepare \[2L\] of its \[0.1M\] aqueous solution is:

    A) \[136.8g\]                      

    B) \[17.1g\]

    C) \[68.4g\]                       

    D) \[34.2g\]

    Correct Answer: C

    Solution :

    \[0.1=\frac{^{n}{{C}_{12}}{{H}_{22}}{{O}_{11}}}{2}\] \[^{n}{{C}_{12}}{{H}_{22}}{{O}_{11}}=0.2\]\[^{Wt}{{C}_{12}}{{H}_{22}}{{O}_{11}}=0.2\times 342=68.4.\]
