(D) Two solutions are isotonic if they have the same osmotic pressure $(\pi = iCRT)$.For $A$: $NaCl$ $(i=2)$,$C=1 \ M \implies \pi \propto 2 	imes 1 = 2$. Urea $(i=1)$,$C=2 \ M \implies \pi \propto 1 	imes 2 = 2$. (Isotonic)For $B$: $CaCl_2$ $(i=3)$,$C=1 \ M \implies \pi \propto 3 	imes 1 = 3$. $KCl$ $(i=2)$,$C=1.5 \ M \implies \pi \propto 2 	imes 1.5 = 3$. (Isotonic)For $C$: $AlCl_3$ $(i=4)$,$C=1.5 \ M \implies \pi \propto 4 	imes 1.5 = 6$. $Na_2SO_4$ $(i=3)$,$C=2 \ M \implies \pi \propto 3 	imes 2 = 6$. (Isotonic)For $D$: $KCl$ $(i=2)$,$C=2.5 \ M \implies \pi \propto 2 	imes 2.5 = 5$. $Al_2(SO_4)_3$ $(i=5)$,$C=1 \ M \implies \pi \propto 5 	imes 1 = 5$. (Isotonic)All $4$ pairs are isotonic.

When does the osmotic pressure of a solution increase?

The osmotic pressure exerted by a solution prepared by dissolving $2.0 \ g$ of protein of molar mass $60 \ kg \ mol^{-1}$ in $200 \ mL$ of water at $27^{\circ} C$ is $.....Pa$. [integer value]
(use $R = 0.083 \ L \ bar \ mol^{-1} \ K^{-1}$)
