Density Lab Report Essay

Introduction Density measures the volume that a given amount of mass takes up. Usually, density has grams per unit volume as a unit. To find the density of an object, the object has to be measured and its mass has to be divided by its volume. Often times, density is used to identify substances, since different elements have specific densities. This experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is performed correctly, the actual density of water will equal the theoretical density of water. In the second section, the density of an aluminum sample will be measured and afterwards compared to the accepted density of aluminum and an unknown sample …show more content…
Afterwards, the flask was filled with distilled water to the mark, so that the bottom of the meniscus is aligned with the ring in the neck of the flask. The filled flask was then weighted and the measure was recorded. Then, the distilled water was poured from the flask into a 50 ml beaker and its temperature was recorded. Once that was done, the flask was cleaned with an unknown solution provided by the instructor and then the flask was filled with the same unknown solution up to the mark. The flask was weighted and its mass recorded. The solution was poured into the waste bin under the hood and the flask was cleaned with distilled …show more content…
These results do not make sense, which indicates that there was a personal careless error. Some personal careless errors might include not being able to completely dry the flask. These results refute the hypothesis since the density obtained in the lab and the accepted density did not
