The osmotic pressure of a sugar solution at $300 \ K$ is $2.46 \ atm$. What is the concentration of the solution (in $M$)?

$A$ solution is prepared by dissolving $0.3 \ g$ of a non-volatile non-electrolyte solute '$A$' of molar mass $60 \ g \ mol^{-1}$ and $0.9 \ g$ of a non-volatile non-electrolyte solute '$B$' of molar mass $180 \ g \ mol^{-1}$ in $100 \ mL$ $H_2O$ at $27^{\circ}C$. Osmotic pressure of the solution will be
[Given: $R=0.082 \ L \ atm \ K^{-1} \ mol^{-1}$] (in $atm$)

Which of the following is $NOT$ used as a semipermeable membrane?

$A$ semipermeable membrane is that which permits the passage of:

What is the osmotic pressure of a solution prepared by dissolving $3 \ g$ of solute in $2 \ dm^3$ of water at $300 \ K$ (in $atm$)? (Molar mass of solute $= 60 \ g \ mol^{-1}$,$R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1}$)

The osmotic pressure of a dilute solution is directly proportional to the
