PURPOSE: A lab report is created to describe the use of common laboratory equipment to examine density of a solid and its composition. (Caution: This is the assignment's purpose as a teaching tool, not the lab's purpose.)The SI unit of density is the kilogram per cubic meter (kg/m 3), but in chemistry density is given in g/L or g/mL. The density units of g/mL equals g/cm 3 since 1 liter equals 1000 cm 3 and 1 mL = 1 cm 3. Grams per liter is the unit reserved for gases, grams per milliliter is used for liquids and solids.The density of the solid was calculated by dividing its mass by its volume, ρ (g/L) = M / V. The mass and volume of the liquid sample were measured and its density was calculated in the same manner as the solid. The calculated densities were compared with the known densities of the solid and liquid.Question: Lab 1.1: Lab Safety and Density Part 1: Lab Safety Introduction It is important to practice safe laboratory procedures even while conducting chemistry labs at home.
