Question

Acetaminophen is the active ingredient in Tylenol. Calculate the mass of carbon in 99.0 g of acetaminophen (CgH9NO₂) NOTE: Round your typed answer to include 2 decimal places.​

Answer 1

6.55 g

Step-by-step explanation:

The atomic mass of Carbon (C) is 12.0107, of Hydrogen (H) is 1.008, of Nitrogen(N) is 14.0067, and of Oxygen(O) is 15.9994

Therefore the molar mass of acetaminophen = 12.0107 + 4 * 1.008 + 14.0067 + 2 * 15.9994 = 151.16

mass of C in 99.0 g of acetaminophen = (99.0 g / 151.16 g/mol) * 1 mol C/ 1mol acetaminophen

mass of C in 99.0 g of acetaminophen = 6.545 g
