Purpose: The purpose of this lab was to find the density of both an unknown liquid and an unknown solid using the most precise and accurate methods possible. Procedures: To find the density of the unknown solid and liquid, the mass and volume of each was measured. The mass of the solid was found by placing it on the electronic scale, closing the compartment, and reading the measurement. To find the volume of the solid, a beaker was filled with water to a precise level. Then the solid was placed into the beaker and the amount of displaced water was recorded. This gave the volume of the solid in milliliters. This was repeated three times. To find the volume of the unknown liquid, a pipette was used to precisely measure 10 milliliters of the liquid. A 30-milliliter beaker was placed on the electronic scale and tared to zero. The measured unknown solution was then added to the beaker on the scale and the mass was recorded. This process was repeated three times. The volume of tap water was then found using a graduated
