- The active ingredient of aspirin tablets is acetylsalicylic acid, which, has a density of 1.4 g/cm3. In a lab class, a student used paper chromatography to isolate another common ingredient of headache remedies. The isolated sample had a mass of 0.384 g and a volume of 0.32 cm3. Given the data in the following table, what was the other ingredient in the headache remedy? Density Values for Potential Headache Remedies Compound Density (g/cm3) White table sugar 0.70 Caffeine 1.2 Acetylsalicylic acid 1.4 Sodium chloride 2.2The density of an irregularly shaped object was determined as follows. The mass of the object was found to be 28.90 g 0.03 g. A graduated cylinder was partially filled with water. The reading of the level of the water was 6.4 cm3 0.1 cm3. The object was dropped in the cylinder, and the level of the water rose to 9.8 cm3 0.1 cm3. What is the density of the object with appropriate error limits? (See Appendix 1.5.)1.)
