Question

If 625g of Tylenol tablet contains 85% acetaminophen, how many moles of acetaminophen are present in the table

Answer 1

625 g X(0.85) = 531.25 g of Acetaminophen in one tablet.
The molecular weight of APAP is 151.17 g/mol
531.25 g (total APAP) X 1 mol/151.17g = 3.5 moles

***The tablets weigh 625 MG, not G. You may want to be sure that's the question. If it is supposed to be MG, then it would be 3.5 mmol (or 0.0035 mol)
