    The density of a solution prepared by dissolving 120 g of urea (mol. mass = 60 u) in 1000 g of water is 1.15 g/mL. The molarity of this solution is :   AIEEE  Solved  Paper-2012

    A) 0.50 M                     

    B) 1.78 M

    C) 1.02 M                     

    D) 2.05 M

    Correct Answer: D

    Solution :

                 Molarity \[=\frac{mols\,of\,solute}{volume\,of\,sol.\,(\ell )}\] \[=\frac{120\times 1.5}{60\times 1120}\times 1000=2.05\]M
