Chem111-105 The Volumetric Pipette Purpose The experiment involving the volumetric pipette was conducted to determine the exact volume contained. The mass of water was measured, as was the density, and then using these acquired figures calculations were made to determine the volume of the water. This particular exercise required the use of the analytical balance to determine the mass of the water, and the volumetric pipette to determine the volume based on the density and temperature. The calculations included mass by difference of the flask and then this was used to determine the actual volume delivered based on the density formula (d = mass ÷ volume). The end result was determined based on the temperature of 24.1 degrees Celsius because volume is sensitive to temperature, unlike mass. The purpose of this experiment was to learn how to use proper glassware to determine accurate and precise measurements. The main concepts that were explore included the idea that density of an object is dependent on temperature, and that the volume of object is a measurement of how much space that specific object takes up.
