Question

2. Acetaminophen (C8H9NO2) is the active ingredient in many nonprescription pain relievers. Each tablet contains 500 mg of acetaminophen, and a typical adult dose is two tablets every eight hours. • Determine the molar mass of acetaminophen (show your work). • Calculate the number of moles of acetaminophen in a single tablet (show your work). • Calculate the number of moles of acetaminophen that an adult would have taken if she took three doses of acetaminophen in one day (show your work).

Answer 1

\[(8*12)+(1*9)+(1*14)+(2*16)= Molar massAcetaminophen\]

\[ molacetaminophen=500mg/Molar massAcetaminophen\]

\[MolAcetaminophen= (500mg*3 doses)/Molar massAcetaminophen\]

That's all you do.. make sense?

Answer 2

@RyanHarp
So the molarmass of acetaminophen= 151, right?
The molacetaminophen is 3.311, right?
The moleacetaminophen is 9.933, right?

Answer 3

yes that looks correct

Answer 4

Okay thanks
