$90 \, g$ of $CH_3COOH$ $(i = 0.5)$ is dissolved in $110 \, g$ of benzene. What will be its osmotic pressure at $300 \, K$ if the density of the solution is $1.2 \, g/mL$? (Answer in $atm$)

$x \ g$ of $MgSO_4$ $(i=1.8)$ in $2.5 \ L$ of solution has an osmotic pressure of $2.463 \ atm$ at $27^{\circ} C$. What is the value of $x$ in $g$?

Assuming complete ionisation,arrange the following solutions in order of increasing osmotic pressure.
$(a)$ $0.5 \ m \ Li_2SO_4$
$(b)$ $0.5 \ m \ KCl$
$(c)$ $0.5 \ m \ Al_2(SO_4)_3$
$(d)$ $0.1 \ m \ BaCl_2$

When $10 \ g$ of glucose (osmotic pressure $P_1$),$10 \ g$ of urea (osmotic pressure $P_2$),and $10 \ g$ of sucrose (osmotic pressure $P_3$) are dissolved in $250 \ mL$ of water,the correct relationship between the osmotic pressures of these solutions is:

Which of the following solutions does not flow in either direction when separated by a semipermeable membrane? (Molar mass: glucose $= 180 \ g \ mol^{-1}$,urea $= 60 \ g \ mol^{-1}$)
