Theo-L1: Measurements and Uncertainty: To produce accurate results in this experiment, conducting the measurements and calculations for this experiment on multiple occasions is recommended. Despite this, it may not always need several attempts; however, it should he noted that the number of measurements performed for a specific measurement and the uncertainty of measurements is proportional. In this experiment, uncertainty is calculated through the instrument used when measuring the dimensions of density. To calculate the uncertainty, the specific measurements produced from an instrument would have an uncertainty of half of the smallest division or increment labelled on that instrument. Density of Materials: The chemical and physical compositions of matter carry distinct properties; regardless of the same or different substances present, they cannot maintain different ratio combinations, equivalent to produce the same density. Therefore, we could use the unique densities of matter as a means to identify them. In this experiment, the following formula was used to determine the density of the unknown material: p=m.-'V The density of the metal represented by \"p\" is calculated from its mass \"m\" and volume \"V\". The mass and volume of the given substance are inverser proportional
