An amine $(\mathrm{X})$ is prepared by ammonolysis of benzyl chloride. On adding p-toluenesulphonyl chloride to it the solution remains clear. Molar mass of the amine $(\mathrm{X})$ formed is $\underline{\hspace{2cm}}$$\mathrm{g} \mathrm{mol}^{-1}$. (Given molar mass in $$\mathrm{gmol}^{-1} \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16, \mathrm{~N}: 14$$)
