The molecular formula of aspirin is C₉H₈O₄.
Molar mass of aspirin = 12×9 + 1×8 + 16×4 = 180 g/mol
Mass of aspirin = 324 mg = 0.324 g
No. of moles of aspirin = (0.324 g)/ (180 g/mol) = 0.0018 mol
Molar mass of aspirin = 12×9 + 1×8 + 16×4 = 180 g/mol
Mass of aspirin = 324 mg = 0.324 g
No. of moles of aspirin = (0.324 g)/ (180 g/mol) = 0.0018 mol
