The osmotic pressure of a living cell is $\displaystyle 12$ atm at $\displaystyle 300$ K . The strength of sodium chloride solution that is isotonic with the living cell at this temperature is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{g} \mathrm{L}^{-1}$. (Nearest integer) Given : $\displaystyle \mathrm{R}=0.08 \mathrm{~L}$ atm $\displaystyle \mathrm{K}^{-1} \mathrm{~mol}^{-1}$ Assume complete dissociation of NaCl (Given : Molar mass of Na and Cl are $\displaystyle 23$ and $\displaystyle 35.5 \mathrm{~g} \mathrm{~mol}^{-1}$ respectively.)
