Calculations: * Calculating the number of moles of Anthracene
Mass of Anthracene Used is 2.018 g
Molar Mass is 178.23 g/mol
Number of moles = MassMolar mass = 2.018 g 178.23gmol = 0.0113 moles * Calculating the number of moles of Maleic Anhydride
Mass of Maleic Anhydride Used is 1.001 g
Molar Mass is 98.06 g/mol
Number of moles = MassMolar mass = 1.001 g 98.06gmol = 0.01021 moles * Calculating the Theoretical Yield
C14H10 + C4H2O3 → C18H12O3

Based on the Number of moles calculated the limiting reagent is the Maleic Anhydride. Theoretical yield = mole of
