In which case does osmosis not occur from solution $A$ to solution $B$?

The osmotic pressure of $1 \, M$ solution at $27 \, ^\circ C$ is ........... $atm$.

Osmotic pressure of $0.1 \ M$ aqueous solution of $MgCl_2$ at $300 \ K$ is $4.92 \ atm$. What will be the percentage ionization of the salt? $.......... \ \%$

The osmotic pressure of a urea solution at $10\,^oC$ is $500\, mm\, of\, Hg$. The solution is diluted such that the temperature increases to $25\,^oC$ and the osmotic pressure becomes $131.6\, mm\, of\, Hg$. By what factor has the solution been diluted?

At $300 \ K$, a one litre solution of sucrose (molecular weight: $342$) was prepared by dissolving $40 \ g$ of sucrose. What is the approximate osmotic pressure (in $kPa$) of the solution at the same temperature? $(R = 8.314 \times 10^6 \ cm^3 \ Pa \ K^{-1} \ mol^{-1})$

Which solution is isotonic with $6 \% \ w/v$ aqueous solution of urea (in $M \ NaCl$)? [Molar mass of Urea $= 60 \ g \ mol^{-1}$]
