The osmotic pressure of a living cell is $12 \, \text{atm}$ at $300 \, \text{K}$. The strength of sodium chloride solution that is isotonic with the living cell at this temperature is _____ $\text{g L}^{-1}$. (Nearest integer)

Given: $R = 0.08 \, \text{L atm K}^{-1} \, \text{mol}^{-1}$

Assume complete dissociation of NaCl

(Given : Molar mass of Na and Cl are $23$ and $35.5 \, \text{g mol}^{-1}$ respectively.)
