In an osmosis process,the volume of the solution:

What is edema?

For a very dilute solution of an electrolyte,which of the following relations is correct? (Assume other parameters are constant)

At $300 \ K$,the osmotic pressure of a solution containing $36 \ g$ of glucose per liter is $4.98 \ bar$. If the osmotic pressure of the solution is $1.52 \ bar$ at the same temperature,what will be its concentration (in $M$)?

Solutions $A, B, C$ and $D$ are respectively $0.2 \ M$ urea,$0.10 \ M$ $NaCl$,$0.05 \ M$ $BaCl_{2}$ and $0.05 \ M$ $AlCl_{3}$. All solutions are isotonic with each other except:

$2.5 \, g$ of protein containing only glycine $(C_2H_5NO_2)$ is dissolved in water to make $500 \, mL$ of solution. The osmotic pressure of this solution at $300 \, K$ is found to be $5.03 \times 10^{-3} \, bar$. The total number of glycine units present in the protein is $....$
(Given : $R = 0.083 \, L \, bar \, K^{-1} \, mol^{-1}$)
