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)

Question diagram: 9 . 3 g of aniline is subjected to reaction with excess of a
Answer:
135
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

nAcetanilide =nAniline 

m135=9.393

m=13.5 g
