Answer:
m = 8.7917 g
Explanation:
This reaction to form the Acetylsalicylic acid, is the following:
C4H6O3 + C7H6O3 --------> C9H8O4 + C2H4O2
Now, the problem already stated that the limiting reactant is the acetic anhydride (C4H6O3), and it's a 1:1 mole ratio, so this means that the moles of acetic anhydride reacting will be the moles of acetylsalicylic acid formed. We have the volume of the anhydride and density, let's calculate the mass, and then, the moles:
d = m/V ------> m = d * V
m = 1.082 * 4.6 = 4.9772 g
The molar mass of C4H6O3 reported is 102.09 g/mol so the moles are:
moles = 4.9772 / 102.09 = 0.0488 moles
As the mole ratio is 1:1 these moles are the same moles of the acid so:
moles Ac Acid = 0.0488 moles
The reported molar mass of the acid is 180.158 g/mol, then the mass:
m = 0.0488 * 180.158 = 8.7917 g
<h2>
m = 8.7917 g</h2><h2>
This is the theorical yield for the reaction</h2>
