Description Pre-Lab Questions: 1.What are the units for mass that are commonly used in the chemistry lab? 2.The typical adult dose of Tylenol (acetaminophen) is 650 mg. Convert this to grams. Clearly show all work (dimensional analysis). 3.Convert 2.5 teaspoons of water to grams of water. Clearly show all work (dimensional analysis). 4.Convert 3 cups of waterto grams of water. Clearly show all work (dimensional analysis). Post-Lab Questions: 1.The density of mercury, a liquid at room temperature, is 13.6 g/mL.What is the mass of a quarter cup of mercury? Show your calculations. 2.Even if you could obtain some mercury, why wouldn’t you want to use it for this lab? 3.Propose another liquid that you could use for this experiment(instead of water). Look up the density of this liquid(in g/mL), and report it here. What are the pros and cons of using this liquid instead of water?
