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

  • question_answer
    The osmotic pressure in atmospheres of 10% solution of canesugar at \[{{69}^{o}}C\] is      [AFMC 1991]

    A)                 724        

    B)                 824

    C)                 8.21       

    D)                 7.21

    Correct Answer: C

    Solution :

             \[\pi V=nRT\]                 \[\pi =\frac{w}{m}\frac{RT}{V}=\frac{10}{342}\times \frac{0.821\times (273+69)}{0.1}\] = 8.21 atm.
