The objective of this experiment is to most accurately and precisely determine the densities of unknown liquids and solids. Some of the instruments we are going to use in this experiment includes: 10 ml pipette , beaker of different sizes (50ml, 100ml, and 200ml), graduated cylinder , electrical balance . Unknown Liquid: Observation - Identification number: 2 Clear content Smalls like paint Data Table - Beaker mass Volume of unknown liquid Beaker + unknown liquid mass Difference (mass of unknown liquid) Trial #1 85.139 grams 10 ml 91.754 grams 6.616 grams Trial #2 85.139 grams 10 ml 91.704 grams 6.565 grams Trial #3 85.140 grams 10 ml 91.378 grams 6..283 grams The volume of the unknown liquid was measured using the pipette, and the mass of liquid was measured using the electric balance. Calculation of the Densities –
