Some Basic Concepts in Chemistry: JEE Main 2024 Chemistry question

$9.3 \mathrm{~g}$ 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 $\mathrm{g} \mathrm{~mol}^{-1}$ $\begin{aligned} & \mathrm{N}: 14, \mathrm{O}: 16, \\ & \mathrm{C}: 12, \mathrm{H}: 1 \text { ) } \end{aligned}$
