We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact

Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to reduce pain and fever. In this experiment it is prepared by the reaction of p-aminophenol with acetic anhydride‚ as illustrated below. Results: Isolation of crude acetaminophen The color
