The density of ' \(x\) ' \(\mathrm{M}\) solution (' \(x\) ' molar) of \(\mathrm{NaOH}\) is \(1.12\mathrm{g}{\mathrm{mL}}^{-1}\), while in molality, the concentration of the solution is \(3\mathrm{m}(3\mathrm{molal})\). Then \(x\) is
(Given : Molar mass of \(\mathrm{NaOH}\) is \(40\mathrm{g}/\mathrm{mol}\) )
