Which statement is wrong regarding osmotic pressure $P$,volume $V$,and temperature $T$?

At a temperature of $27\,^oC$,$0.6\,g$ of a solute is dissolved in $0.1\,L$ of solvent,resulting in an osmotic pressure of $1.23\,atm$. The molar mass of the solute is .......... $g\,mol^{-1}$.

Give an example of a material used for making a semipermeable membrane for carrying out reverse osmosis.

The empirical formula of a non-electrolyte is $CH_{2}O$. $A$ solution containing $6 \ g$ of the compound exerts the same osmotic pressure as that of $0.05 \ M$ glucose solution at the same temperature. The molecular formula of the compound is

What is the osmotic pressure $(\pi)$ of a $0.02 \ M$ solution of $NaCl$ (in $RT$)?

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-$II$ $(atm)$ |
| :--- | :--- | :--- |
| $I$ | $2.0$ | $1.0$ |
| $II$ | $1.0$ | $2.0$ |
| $III$ | $3.0$ | $1.0$ |
| $IV$ | $1.0$ | $1.0$ |
