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?

Which of the following statements is correct for an aqueous solution of $6 \ g \ L^{-1}$ urea and $17.12 \ g \ L^{-1}$ sucrose? [Molar mass of urea $= 60 \ g \ mol^{-1}$,Molar mass of sucrose $= 342 \ g \ mol^{-1}$]

$A$ $40 \text{ g}$ non-electrolyte solute having a molar mass of $180 \text{ g mol}^{-1}$ is dissolved in water to form a solution. If the osmotic pressure of the solution is $2 \text{ atm}$ at $300 \text{ K}$, calculate the volume of the solution in $\text{dm}^3$. $(R = 0.0821 \text{ L atm K}^{-1} \text{mol}^{-1})$ (in $\text{ dm}^3$)

$A$ solution of a non-electrolyte substance containing $1.05 \ g$ per $100 \ mL$ was found to be isotonic with a $3\%$ glucose solution. The molecular mass of the substance is:

The solution in which the blood cells retain their normal form is with regard to the blood:
