The process in which solvent molecules pass through a semipermeable membrane is called:

$A$ graph of osmotic pressure $(\pi)$ vs molarity $(M)$ of an aqueous solution of $NaCl$ at room temperature is given below. The slope of the line represents :-

Calculate the osmotic pressure of a solution prepared by dissolving $1.75 \ g$ of glucose $(C_6H_{12}O_6)$ in $150 \ mL$ of solution at $17 \ ^oC$. (in $atm$)

$A$ solution containing $10 \, g \, dm^{-3}$ of urea $(M.wt = 60)$ is isotonic with a $5 \%$ solution of a non-volatile solute. The molecular mass of this non-volatile solute is ......... $g \, mol^{-1}$.

Calculate the osmotic pressure of a $20\%$ (w/v) anhydrous $CaCl_2$ solution at $0^\circ C$. Assume $100\%$ ionization. (in $\text{atm}$)

$A$ $0.002 \, M$ solution of $NaCl$ having a degree of dissociation of $90 \%$ at $27 \, ^{\circ}C$ has an osmotic pressure equal to:
