4. Based on the mole ratio of the reaction (1:1 for the reactants), determine which reactant is the limiting reagent, based on the amounts you will be using as shown under “Reagents” above. Show your work. (Note: the density for the acetic anhydride solution is 1.08 g/mL)
The amounts for p-aminophenol is 1.5 g, and the amounts for acetic anhydride is 2.5 g in 7.5 mL of water. The molar mass of p-aminophenol is 109.14 g/mol. The molar mass for acetic anhydride is 102.09 g/mol. The molar mass for acetaminophen is 151.163 g/mol. The acetic acid molar mass is 60.052 g/mol.
