$A$ $5 \%$ solution of cane sugar (mol. wt. $= 342$) is isotonic with $1 \%$ solution of a substance $X$. The molecular weight of $X$ is

Identify the correct statement regarding $0.2 \text{ M}$ urea and $0.2 \text{ M}$ sucrose solutions.

What is edema?

$A$ solution containing $10 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) per liter is isotonic with a $5 \% \ w/v$ solution of a non-volatile solute. The molar mass of the non-volatile solute is ......... $g \ mol^{-1}$.

$A$ solution of a nonvolatile solute is obtained by dissolving $0.8 \ g$ in $0.3 \ dm^3$ of water. The solution has an osmotic pressure of $0.2 \ atm$ at $300 \ K$. Calculate the molar mass of the solute. $[R = 0.082 \ atm \ dm^3 \ K^{-1} \ mol^{-1}]$

Find the amount of solute in a solution obtained by dissolving it in $2.5 \ dm^3$ of water that generates an osmotic pressure of $0.245 \ atm$ at $300 \ K$. (Molar mass of solute $= 58 \ g \ mol^{-1}$,$R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1}$) (in $g$)
