    The osmotic pressure of blood is \[7.65\]atm at \[{{37}^{o}}C\]. How much glucose should be used per litre for an intravenous injection that is to have the same osmotic pressure as blood?

    A)  \[180\text{ }g\]                      

    B)  \[54.2\text{ }g\]

    C)  \[86\text{ }g\]                        

    D)  \[\text{111 }g\]

    Correct Answer: B

    Solution :

    \[n=\frac{\pi V}{RT}\] \[=\frac{7.65\times 1}{0.0821\times 310}=0.301\,mol\] Weight of glucose used             \[=0.301\times 180g=54.2g\]
