    A living cell contains a solution which is isotonic with 0.3 (M) sugar solution. What osmotic pressure develops when the cell is placed in 0.1 (M) KCl solution at body temperature?

    A) 5.08 atm          

    B) 2.54 atm

    C) 4.92 atm          

    D) 2.46 atm

    Correct Answer: B

    Solution :

    [b] \[\pi =({{i}_{1}}{{c}_{1}}-{{i}_{2}}{{C}_{2}})RT\] \[=(1\times 0.3-2\times 0.1)\times 0.082\times 310\] \[=2.54atm\]
