The osmotic pressure of a $5\% \ (w/V)$ solution of cane sugar at $150\,^{\circ}C$ will be $.......$ $atm$.

At $27^{\circ}C$,a solution containing $2.5 \ g$ of solute in $250.0 \ mL$ of solution exerts an osmotic pressure of $400 \ Pa$. The molar mass of the solute is $.............. \ g \ mol^{-1}$ (Nearest integer) (Given: $R = 0.083 \ L \ bar \ K^{-1} \ mol^{-1}$)

The osmotic pressures of $0.010 \ M$ solutions of $KI$ and of sucrose $(C_{12}H_{22}O_{11})$ are $0.432 \ atm$ and $0.24 \ atm$ respectively. The van't Hoff factor for $KI$ is

$A$ $0.6 \%$ solution of urea (molecular mass $= 60$) would be isotonic with

$200 \ mL$ of an aqueous solution of a protein contains its $1.26 \ g$. The osmotic pressure of this solution at $300 \ K$ is found to be $2.57 \times 10^{-3} \ bar$. The molar mass of protein will be ......... $g \ mol^{-1}$.
$(R = 0.083 \ L \ bar \ mol^{-1} \ K^{-1})$

Correct order of osmotic pressure of the following solutions is
$(i)$ $30 \ g \ L^{-1}$ of glucose
$(ii)$ $60 \ g \ L^{-1}$ of $NH_2CONH_2$
$(iii)$ $80 \ g \ L^{-1}$ of glucose
$(iv)$ $58.5 \ g \ L^{-1}$ of $NaCl$
