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....

A student reacts 4.00g of aniline (MW= 93.24g/mol) with 5.40mL of acetic anhydride (MW= 102.07 g/mol, p= 1.082 g/ml) which produces 4.23g of acetanilide (MW= 135.18g/mol). a.) How many moles of aniline are used in the reaction? b.) What mass of acetic anhydride is used in this reaction? c.) How many moles of acetic anhydride are used in the reaction? d.) What is the limiting reagant in this reaction? e.) How many moles of acetanilide are made in the reaction?...
