If a tablet of acetaminophen,C₈H₉NO₂,weighs 324 mg,how many moles are there in the tablet?

Question

Quizplus · Accepted Answer

The molecular formula for acetaminophen is C8H9NO2. Calculating its molar mass: (12.01*8) + (1.01*9) + (14.01*1) + (16.00*2) = 151.17 g/mol. The number of moles in 324 mg (0.324 g) is calculated by dividing the mass by the molar mass: 0.324 g / 151.17 g/mol = 2.14 × 10^-3 moles, which rounds to 2.15 × 10^-3 moles, matching option A.
