Osmotic pressure is $0.0821 \ atm$ at a temperature of $300 \ K$. Find the concentration in $mol/L$.

Which of the following methods is used to obtain pure water from seawater?

Blood has been found to be isotonic with

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

Which one of the following solutions of compounds shows the highest osmotic pressure? ($AB, AB_2$ and $A_2 B_3$ are ionic compounds)

Given below are two statements:
Statement $I$: $H_2O$ molecules move from the chamber $1$ to chamber $2$.
Statement $II$: The osmotic pressure of a solution prepared by dissolving $50 \text{ mg}$ of potassium sulphate (molar mass = $174 \text{ g/mol}$) in $2 \text{ L}$ of water (at $27^{\circ}C$) is $0.0107 \text{ bar}$. (Given: $R = 0.083 \text{ dm}^3 \text{ bar K}^{-1} \text{ mol}^{-1}$ and assume complete dissociation of electrolyte).
In the light of the above statements, choose the correct answer from the options given below:
