Calorimetry Volume Lab

In the volume lab, we found that the large graduated cylinder was the most accurate because it had less percent error when measuring the density of water over all of the other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the pipettes in milliliters, the initial mass of the beaker without water in grams, and the final mass of the beaker with water in grams. We did this procedure again, and also tested the temperature of the water with the graduated cylinders, erlenmeyer flasks, and the beakers of the second trial. The first trial, with the 10 milliliters volumetric pipette, showed the volume to be 14 milliliters, 50.78 grams for the initial mass, and 60.68 grams for the final mass. The second trial, with the 5 milliliters volumetric pipette, …show more content…
For example, a volumetric pipette may be the most logical piece of equipment if the substance being measured needed to be moved from one container to another. Using the volumetric pipette would allow us to not only move the substance easier, but it also takes moderately accurate measurements. A specific situation in which a volumetric pipette would work better than the large graduated cylinder could be if a chemical is being moved from its beaker to an erlenmeyer flask to be heated. The volumetric pipette would measure the chemical safely and accurately while allowing us to transport it to the beaker safely. This is just one situation in which a certain circumstance calls for a different piece of equipment other than the large graduated cylinder to be used, even though it is the most
