$A$ solution containing $8.6 \ g$ of urea per liter is isotonic with a $0.5\% \ (w/v)$ solution of a non-volatile organic solute. What is the molar mass of the organic solute?

If a thin slice of sugar beet is placed in a concentrated solution of $NaCl$,then...

The size of a raw mango shrinks to a much smaller size when kept in a concentrated salt solution. Which one of the following processes can explain this?

$A$ solution is prepared by dissolving $0.6 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) and $1.8 \ g$ of glucose (molar mass $= 180 \ g \ mol^{-1}$) in $100 \ mL$ of water at $27 \ ^oC$. The osmotic pressure of the solution is : ............. $atm$ $(R = 0.08206 \ L \ atm \ K^{-1} \ mol^{-1})$

The osmotic pressure of $0.4\%$ urea solution is $1.66\ atm$ and that of a solution of sugar of $3.42\%$ is $2.46\ atm$. When both the solutions are mixed in equal volumes,then the osmotic pressure of the resultant solution will be ......... $atm$.

If osmotic pressure of a solution is $2 \ atm$ at $273 \ K$,then at $546 \ K$,the osmotic pressure is ........... $atm.$
