The osmotic pressure of a $1 \ M$ solution at $27^{\circ}C$ is $(R = 0.082 \ L \ atm \ K^{-1} \ mol^{-1})$: (in $atm$)

$0.5 \ M$ $P_3Q_2$ $(i = 5)$ and $0.01 \ M$ $M_2N_3$ $(i = 5)$ are separated by a semipermeable membrane $AB$ in an aqueous solution as shown. These solutes react to give a brown color. Due to osmosis,there is:

$A$ solution of sodium chloride with a concentration of ...... is isotonic with the fluid inside human red blood cells.

The average osmotic pressure of human blood is $7.8 \ bar$ at $37\ ^oC$. What is the concentration of an aqueous $NaCl$ solution that could be used in the blood stream (in $mol/L$)?

$1.46 \, g$ of a biopolymer dissolved in a $100 \, mL$ water at $300 \, K$ exerted an osmotic pressure of $2.42 \times 10^{-3} \, bar$.
The molar mass of the biopolymer is $..... \times 10^{4} \, g \, mol^{-1}$. (Round off to the Nearest Integer)
[Use : $R = 0.083 \, L \, bar \, mol^{-1} \, K^{-1}$ ]

Calculate the osmotic pressure of a $0.2 \ M$ aqueous solution of an electrolyte at $300 \ K$. If the van't Hoff factor is $1.6$,find the osmotic pressure. $\left[R=0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}\right]$ (in $atm$)
