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

At a certain temperature,the osmotic pressure of a $0.25 \, M$ solution of a non-electrolyte is $\pi \, bar$. What will be the osmotic pressure of a $0.125 \, M \, Ba(NO_3)_2$ solution at the same temperature?

What is osmotic pressure? Explain and derive its equation.

The osmotic pressure of a sugar solution at $24^{\circ}C$ is $2.5 \ atm$. What is the concentration of the solution in moles per litre?

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? $(R = 8.314 \times 10^6 \ cm^3 \ Pa \ K^{-1} \ mol^{-1})$
