9 . 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 100 % completed is _____ × 10 - 1 g . (Given molar mass in g mol - 1 N = 14 , O = 16 , C = 12 , H = 1 )

Correct answer

0

Step-by-step solution

Given, Aniline required. is 9 . 3 gms Molar mass of aniline= 93 g mol - 1 Molar mass of Acetanilide = 135 g mol - 1 The reaction is given as, Number of moles=Mass / Molar mass n Acetanilide = n Aniline ⇒ m 135 = 9 . 3 93 ⇒ m = 13 . 5 g
