Show work please!!!
3. The production of acetanilide involves the treatment of aniline (an aromatic amine) with acetic anhydride. This reaction produces an amide called acetanilide and acetic acid (byproduct). The reaction is as follows: NH2 NCH acetic acid HCOCH Наслон aniline acetic anhydride acetanilide CH, C4H603 CgH9NO C2H4O2 93.139 102.09 . mol mol Since aniline is a liquid, conversion from milliliters to grams will yield the equivalence of 4.000 grams of aniline. 135.16 9 60.05 9 mol mol a....
