JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Osmosis and Osmotic pressure of the solution

  • question_answer
    Osmotic pressure is 0.0821 atm at temperature of \[300\,K\]. Find concentration in mole/litre   [Roorkee 1990]

    A)                 0.033     

    B)                 0.066

    C)             \[0.33\times {{10}^{-2}}\]          

    D)                 3

    Correct Answer: C

    Solution :

                \[\pi =CRT\], \[C=\frac{\pi }{RT}=\frac{0.0821}{0.821\times 300}=0.33\times {{10}^{-2}}\].
