    A 0.5 g/L solution of glucose is found to be isotonic with a 2.5 g/L solution of an organic compound. What will be the molecular weight of that organic compound?

    A)  300                                       

    B)  600                       

    C)  900                       

    D)         200

    Correct Answer: C

    Solution :

    Molarity of glucose solution \[=\frac{0.5g}{180\times 1L}=0.00277\,M\] Isotonic   solution   have   equal   molar concentrations, hence molarity of organic compound solution = 0.00277 M \[\therefore \] Molecular weight of compound \[=\frac{2.5}{0.00277\times 1}=900\]
