Salicylic acid (c7h6o3) reacts with acetic anhydride (c4h6o3) to form acetylsalicylic acid (c9h8o4). 2c7h6o3(aq) + c4h6o3(aq) mc002-1.jpg 2c9h8o4(aq) + h2o(l) what is the limiting reactant if 70.0 g of c7h6o3 and 80.0 g of c4h6o3 react?

In order to understand what is the limiting reactant is useful to convert the masses of reactants into moles. The molecular masses are:



Converting masses into moles:





In the reaction, 2 moles of are necessary to react with 1 mol of . Following this ratio:



We have only 0.5 mol of , i.e, we don't have enough amount of salicylic acid, therefore, this is the limiting reactant.

Cause its being chemically applied?
