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

What is the relationship between the osmotic pressures of $6.00 \ g \ L^{-1}$ $CH_3COOH$ $(\pi_1)$ and $7.45 \ g \ L^{-1}$ $KCl$ $(\pi_2)$ solutions?

$x \ g$ of $MgSO_4$ $(i=1.8)$ in $2.5 \ L$ of solution has an osmotic pressure of $2.463 \ atm$ at $27^{\circ} C$. What is the value of $x$ in $g$?

The osmotic pressure of blood is $7.47 \, bar$ at $300 \, K$. To inject glucose to a patient intravenously,it has to be isotonic with blood. The concentration of glucose solution in $g \, L^{-1}$ is $......$ (Molar mass of glucose $= 180 \, g \, mol^{-1}$,$R = 0.083 \, L \, bar \, K^{-1} \, mol^{-1}$) (Nearest integer)

Which inorganic precipitate acts as a semipermeable membrane,or what is the chemical composition of a semipermeable membrane?

$A$ solution of sucrose (molar mass $= 342 \ g \ mol^{-1}$) is prepared by dissolving $68.4 \ g$ of it per litre of the solution. What is its osmotic pressure in $atm$ at $273 \ K$? (Given: $R = 0.082 \ L \ atm \ K^{-1} \ mol^{-1}$)
