9.3g9 . 3g of aniline is subjected to reaction with excess of acetic anhydride to prepare acetanilide. The mass of acetanilide produced if the reaction is 100100 % completed is _____×10−1g\times {10}^{- 1}g.

(Given molar mass in gmol−1N=14,O=16,C=g{mol}^{- 1}N = 14, O = 16, C =12,H=1)12, H = 1 )

9 . 3g of aniline is subjected to reaction with excess of acetic anhydride to prepare acetanilide. The mass of

Correct answer

0

Step-by-step solution

Given, Aniline required. is 9.3gms9 . 3gms

Molar mass of aniline= 93gmol−193g{mol}^{- 1}

Molar mass of Acetanilide = 135gmol−1135g{mol}^{- 1}

The reaction is given as,

9 . 3g of aniline is subjected to reaction with excess of acetic anhydride to prepare acetanilide. The mass of

Number of moles=Mass / Molar mass

nAcetanilide=nAniline{n}_{\text{Acetanilide}} = {n}_{\text{Aniline}}

⇒m135=9.393⇒ \dfrac{m}{135} = \dfrac{9 . 3}{93}

⇒m=13.5g⇒ m = 13 . 5g
