What is the percent yield of aspirin? Is my work correct?

  Mass (g)
Empty flask  92.612 g
Flask and salicylic acid  94.604 g
Salicylic acid  1.992 g 
#1 filter paper 0.721 g
#1 filter paper + unrecrystallized aspiring  3.987 g
Unrecrystallized aspiring  3.266 g
#2 filter paper 0.722 g
#2 filter paper + recrystalized aspirin 1.258 g
Recrystallized aspirin 0.536 g 

This is what I got

  • salicylic acid mol 
    • 1.992 g/ 138.121 g/mol = 0.01442214 mol
  • aspirin mol
    • 0.01442214 mol x (1 mol/ 1 mol) = 0.01442214 mol
  • aspiring grams 
    • 0.01442214 mol x 180.158 g/mol = 2.5981306 g 
  • percent yeild 
    • (0.536 g/2.5981306 g) x 100 = 20.630218%
