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