When a concentrated solution of sulphanilic acid and $\displaystyle 1$-naphthylamine is treated with nitrous acid ($\displaystyle 273$ K) and acidified with acetic acid, the mass (g) of $\displaystyle 0.1$ mole of product formed is : (Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{H}: 1, \mathrm{C}: 12, \mathrm{~N}: 14, \mathrm{O}: 16, \mathrm{~S}: 32$ )
