  • question_answer
    2.0 molar solution is obtained , when 0.5 mole solute is dissolved in                                           [MP PMT 2003]

    A)                 250 ml solvent     

    B)                 250 g solvent

    C)                 250 ml solution    

    D)                 1000 ml solvent

    Correct Answer: C

    Solution :

           We know that            Molarity \[=\frac{\text{Number  of moles of solute}}{\text{Volume of solution in }litre}\]            \[\therefore 2.0=\frac{0.5}{\text{Volume of solution in}\,\,litre}\]            \ Volume of solution in litre                        \[=\frac{0.5}{2.0}=0.250litre=250\,ml.\]
