$\displaystyle 3$ g of aniline is subjected to reaction with excess of acetic anhydride to prepare acetanilide. The mass of acetanilide produced if the reaction is $\displaystyle 100$% completed is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-1} \mathrm{~g}$. (Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$ N : $\displaystyle 14$, O : $\displaystyle 16$, C : $\displaystyle 12$, H : $\displaystyle 1$)
