    An aqueous solution containing \[1g\]urea I boils at\[{{100.25}^{o}}C\]. The aqueous solution containing \[3g\]of glucose in the same volume will boil at:

    A)  \[{{100}^{o}}C\]              

    B)  \[{{100.5}^{o}}C\]

    C)  \[{{100.25}^{o}}C\]                        

    D)  \[{{100.75}^{o}}C\]

    Correct Answer: C

    Solution :

    Sol.         Moles of urea \[=\frac{1}{60}\] Moles of glucose \[=\frac{3}{180}\]                                 \[=\frac{1}{60}\] Since, molar concentration are same, the boiling point will also be same.
