    No of moles of aspirin = No of mole of NaOH – No of mole of HCl
    (M x V) NaOH – (M x V) HCl
    (0.1M x 21.20ml) – (0.04M x 21.80ml)
    1.248mmoles
    Mass of aspirin = 180.157g/mol x 1.248mmoles = 224.8359mg
    224.8359mg x 1g/1000mg = 0.2248g of Aspirin
    Since, 0.102g Aspirin powder contains 0.2248 aspirin, what is the mass percent of aspirin in the tablet?
    0.2248g/0.300g x 100 = 74.9%
