What is the osmotic pressure of a $12\%$ solution of cane sugar (molecular weight $342$) at $17\,^oC$ (in $,atm$)?

The relationship between osmotic pressure at $273 \ K$ when $10 \ g$ glucose $(P_1)$,$10 \ g$ urea $(P_2)$,and $10 \ g$ sucrose $(P_3)$ are dissolved in $250 \ mL$ of water is:

Calculate the temperature of $0.05 \ M$ sucrose solution in Kelvin if the osmotic pressure of the solution is $1.5 \ atm$. $[R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1}]$

$A$ $40 \text{ g}$ non-electrolyte solute having a molar mass of $180 \text{ g mol}^{-1}$ is dissolved in water to form a solution. If the osmotic pressure of the solution is $2 \text{ atm}$ at $300 \text{ K}$, calculate the volume of the solution in $\text{dm}^3$. $(R = 0.0821 \text{ L atm K}^{-1} \text{mol}^{-1})$ (in $\text{ dm}^3$)

Assertion $(A)$: Blood cells collapse when suspended in saline water.
Reason $(R)$: Cell membrane dissolves in saline water.

The ideal method to determine osmotic pressure is ...... .
