Aspirin (c9h8o4) is synthesized by reacting salicylic acid (c7h6o3) with acetic anhydride (c4h6o3) according to the reaction: c7h6o3 + c4h6o3 --> c9h8o4 + hc2h3o2 a. what mass of acetic anhydride is needed to completely react 1.00 x 10 4 g of salicylic acid?

of acetic anhydride is needed

Explanation:

According to balanced equation, 1 mol of salicylic acid completely reacts with 1 mol of acetic anhydride

Number of moles = (mass)/(molar mass)

Molar mass of acetic anhydride = 102.09 g/mol

Molar mass of salicylic acid = 138.121 g/mol

So, of salicylic acid = of salicylic acid

Hence, of salicylic acid reacts completely with of acetic anhydride.

So, mass of acetic anhydride needed = =
