How many grams of glucose must be added to $0.5 \ L$ of a solution so that its osmotic pressure is same as that of a solution of $9.2 \ g$ of glucose dissolved in a liter?

Find the osmotic pressure of a $0.01 \text{ M}$ solution at $25 \text{ }^\circ\text{C}$ $(R = 0.0821 \text{ L atm mol}^{-1} \text{K}^{-1})$. (in $\text{ atm}$)

$A$ $5\% \text{ (w/v)}$ solution of cane sugar (molar mass = $342 \text{ g/mol}$) is isotonic with a $1\% \text{ (w/v)}$ solution of an unknown solute. What is the molar mass of the unknown solute in $\text{g/mol}$?

The osmotic pressure of blood at $300 \ K$ is $8.21 \ atm$. What is the concentration of an aqueous glucose solution that is isotonic with this blood in $g \ L^{-1}$?

The empirical formula of a non-electrolyte is $CH_2O$. $A$ solution containing $3 \ g$ of the compound exerts the same osmotic pressure as that of $0.05 \ M$ glucose solution. The molecular formula of the compound is

At a certain temperature,a $1.6 \%$ solution of an unknown substance is isotonic with a $2.4 \%$ solution of Urea. If both solutions have the same solvent and the same density of $1 \ g/cm^3$,what is the molecular mass of the unknown substance in $g/mol$? [Molecular mass of urea $= 60 \ g/mol$]
