First, we need to make sure we have both mass values of the reactant.
The mass of C 7H6O3 is already given so we only need to calculate the mass of (CH3CO)2O using the volume and density given:
Aspirin (acetylsalicylic acid, C9H8O4) is made by reacting salicylic acid (C 7H6O3) with acetic anhydride [(CH3CO)2O]: C7H6O3(s) + (CH3CO)2O(l) ⟶C9H8O4(s) + CH3COOH(l) In one preparation, 3.077 g of salicylic acid and 5.50 mL of acetic anhydride react to form 3.281 g of aspirin.
(a) Which is the limiting reactant (the density of acetic anhydride is 1.080 g/mL)?
