    The osmotic pressure of a 5% (wt./vol) solution of cane sugar at\[150{{\,}^{o}}C\]is

    A) \[\text{ }\!\!~\!\!\text{ 3}\text{.078 atm}\]        

    B)  \[\text{4}\text{.078 atm}\]

    C)  \[5.078\,\text{atm}\]

    D) \[2.45\,\text{atm}\]

    Correct Answer: C

    Solution :

     \[C=\frac{5}{342}\times \frac{1}{100}\times 1000\] \[\text{C}\,\text{=}\frac{\text{50}}{\text{342}}\text{mol/L}\] \[\pi \,\text{= CRT=}\frac{50}{342}\times 0.082\times 423=5.07\,\text{atm}\]
