$9.3 \mathrm{~g}$ of aniline is subjected to reaction with excess of acetic anhydride to prepare acetanilide. The mass of acetanilide produced if the reaction is _________$100 \%$ completed is $\times 10^{-1} \mathrm{~g}$. (Given molar mass in $\mathrm{g} \mathrm{mol}^{-1} \mathrm{~N}: 14, \mathrm{O}: 16, \mathrm{C}$ : $12, \mathrm{H}: 1)$
$9.3 \mathrm{~g}$ of pure aniline is treated with bromine water at room temperature to give a white precipitate of the product ' $\mathrm{P}$ '. The mass of product ' $\mathrm{P}$ ' obtained is $26.4 \mathrm{~g}$. The percentage yield is ......... $%$.
