1.86 gm of aniline is converted into acetanilide with 90% efficiency. Mass of acetanilide formed
is
[X]×10−2gm
243×10−2
(C6H7N) Acetanilide (C6H7N)
1.86 g
Molar mass =93 Molar mass =135
∗ 93 g aniline produces 135 g acetanilide
1.86 g aniline produces
135×1.8693=2.70g
∗ At 90% efficiency of reaction it produces =2.70×90100=2.43g
Ans. 243×10−2
