Procedure and Data Density of Volatile Substance 1. Measure the mass of the empty glass beaker to 0.01 g. 2. Add 5.0-mL of your acetone or isopropyl alcohol using the PLASTIC PIPET (do not use the plastic graduated cylinder as it can ruin it and the markings.) You will have to do this in 1mL increments like in the previous lab. 3. Obtain the mass of the beaker and the solvent added. 4. Add an additional 5mL of the solvent and then re-record the mass. 5. Calculate the density of the two trials. Find the average density and percent error for your solvent. Substance Used: Isopropyl alcohol 1. Mass of beaker 2. Mass of beaker from first 5.00mL addition 3. Mass of beaker from second 5.00mL addition 4. Mass of solvent from each addition (#2-1) and (#3-2) 5. Calculated density of solvent Volume Used: 5.00mL 79.59q 84.13g 88-489 4.549 4.35g
