    The osmotic pressure at \[{{17}^{o}}C\] of an aqueous solution containing 1.75 g of sucrose per 150 ml solution is [BHU 2001]

    A)                 0.8 atm  

    B)                 0.08 atm

    C)                 8.1 atm  

    D)                 9.1 atm

    Correct Answer: A

    Solution :

               \[\pi =CRT\,=\frac{n}{V}RT\]\[=\frac{\frac{1.75}{342}}{\frac{150}{1000}}\times 0.0821\times 290\]                            \[=0.8095\approx 0.81\,atm\].
