Fatima Elzin SJU Chem 1111L 09/18/2009 Dr. Pedro Bastos Methods for the Determination of Density Part I 1. Which is more precise, the density derived from the calculated volume or the density derived from the measured volume? The density derived from the calculated volume is more precise that the density of the measured volume. Unlike the density of the measured volume, the calculated volume is derived using the vernier calipers which is much more precise then the water displacement method using the graduated cylinder. Unlike the measured volume, we don’t need to take in account the possibility that water may have spilled during the process of the calculated volume. Part II 1. How would you determine the density of a gas? To determine the density of a gas you must use an empty vessel and measure its volume and mass. Then fill the vessel with the gas and measure its volume again. Then you the equation density=mass/volume and then you can determine the density. 2.
