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