    What is the amount of urea dissolved per litre if aqueous solution is isotonic with 10% cane sugar solution? (mol. wt. of urea = 60)

    A)  200g/L                                 

    B)  19.2g/L

    C)  17.54g/L                             

    D)  16.7g/L

    Correct Answer: C

    Solution :

                     \[{{V}_{1}}=1\,{{L}_{2}}{{V}_{3}}=100\,mL=0.1L\] \[\frac{{{W}_{1}}}{{{m}_{1}}{{V}_{1}}}=\frac{{{W}_{2}}}{{{m}_{2}}{{V}_{2}}}\] \[\frac{{{W}_{1}}}{60\times 1}=\frac{10}{342\times 0.1}\] \[{{W}_{1}}=17.54\,g/L\]
