When two solutions $X$ and $Y$ are separated by a semi-permeable membrane and the solvent flows from $Y$ to $X$,then:

In a container,$0.1 \, M \, NaCl$ and $0.05 \, M \, BaCl_2$ solutions are separated by a semi-permeable membrane. Which of the following is correct?

The osmotic pressure of sea water is $1.05 \ atm$. Four experiments were carried out as shown in the table below. In which of the following experiments can pure water be obtained in part-$II$ of the vessel?
| Experiment | Pressure applied on part-$I$ $(atm)$ | Pressure applied on part-$II$ $(atm)$ |
| :--- | :--- | :--- |
| $I$ | $2.0$ | $1.0$ |
| $II$ | $1.0$ | $2.0$ |
| $III$ | $3.0$ | $1.0$ |
| $IV$ | $1.0$ | $1.0$ |

Calculate the concentration of an aqueous solution of a non-electrolyte at $300 \ K$ if its osmotic pressure is $12 \ atm$. $\left[R = 0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}\right]$ (in $M$)

At which temperature does a $0.006\% \ w/V$ urea solution have an osmotic pressure of $0.0246 \ atm$ (in $K$)?

$A$ solution containing $8.6 \ g$ of urea per liter is isotonic with a $0.5\% \ (w/v)$ solution of a non-volatile organic solute. What is the molar mass of the organic solute?
