The melting point range of p-aminophenol is 187 degree C -188 degree C. A sample of acetaminophen, synthesized in the lab, was determined to have a melting point rang of 167 degree C - 170 degree C. This is an indication that the sample is: pure acetaminophen a mixture of both acetaminophen and p-aminophenol pure p-aminophenol slightly impure acetic anhydride
