Question

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 ______ \(\times 10^{-1}g.\)

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

Answer 1

Correct answer is : 135

\(n_{Ace\,tan\,ilide}= n_{Aniline}\)

\(\Rightarrow \frac {m}{135} =\frac {9.3}{93}\) 

\(\Rightarrow m = 13.5 g\)
