3. How many grams and atoms of carbon are present in 500 grams of acetaminophen (C₂H9NO₂), which has a molar mass relative to your answer from number 2? Show your solution in dimensional analysis below. (1 mole = 6.022 x 10²3 particles) Mole of C atoms= Mass of Catoms= Number of C atoms= mol .8 particles 4. An unknown compound is analyzed and found to consist of 24.3 % carbon, 4.1 % hydrogen, and 71.6 % chlorine. If the molar mass of the compound is 98.8 g/mol, what is the molecular formula of the compound?
