. . . . . . solution is hypertonic with reference to fluid inside the blood cell.

At constant temperature,the osmotic pressure of a solution is:

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

Which method is used to remove salt from sea water?

$x \% (w/v)$ solution of urea is isotonic with $4 \% (w/v)$ solution of a non-volatile solute of molar mass $120 \ g \ mol^{-1}$. The value of $x$ is

$300 \ mL$ of an aqueous solution of a protein contains $2.52 \ g$ of the protein. If the osmotic pressure of such a solution at $300 \ K$ is $5.04 \times 10^{-3} \ bar$,the molar mass of the protein in $g \ mol^{-1}$ is:
