JEE MAIN - Chemistry (2024 - 27th January Evening Shift - No. 27)
$$9.3 \mathrm{~g}$$ 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 $$\mathrm{g} \mathrm{~mol}^{-1}$$
$$\begin{aligned} & \mathrm{N}: 14, \mathrm{O}: 16, \\ & \mathrm{C}: 12, \mathrm{H}: 1 \text { ) } \end{aligned}$$
Answer
135
Explanation

$$\begin{aligned} & \mathrm{n}_{\text {Acetan ilide }}=\mathrm{n}_{\text {Aniline }} \\ & \Rightarrow \frac{\mathrm{m}}{135}=\frac{9.3}{93} \\ & \Rightarrow \mathrm{m}=13.5 \mathrm{~g} \end{aligned}$$
