$A$ $3\% \, w/v$ aqueous solution of urea is isotonic with a $5\% \, w/v$ aqueous solution of another solute. Assuming the van't Hoff factor for the solute is $1.0$,calculate the molar mass of the solute in $g/mol$.

The solution containing $4.0 \ g$ of a polyvinyl chloride polymer in $1 \ L$ of dioxane was found to have an osmotic pressure of $6.0 \times 10^{-4} \ atm$ at $300 \ K$. Given $R = 0.082 \ L \ atm \ mol^{-1} \ K^{-1}$,the molecular mass of the polymer is:

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

Which of the following is the correct order of osmotic pressure for solutions containing equal moles of glucose,$NaCl$,and $BaCl_2$?

The osmotic pressure of a dilute solution is $7 \times 10^5 \ Pa$ at $273 \ K$. Osmotic pressure of the same solution at $283 \ K$ is . . . . . . . $\times 10^4 \ Nm^{-2}$.

In a container,$0.1 \, M \, NaCl$ and $0.05 \, M \, BaCl_2$ solutions are separated by a semi-permeable membrane. Which of the following is correct?
