Density is the state or quality of being dense. Volume is the amount of space that an object or substance occupies. Mass is commonly measure by how much an object weighs. These are the measurements needed to be computed by the group through conducting an experiment. The group computed the measurements of different liquids and solids. The liquids are water, liquid petroleum, ethanol, isopropyl alcohol, and the solids are eight (8) identical coins and a styrofoam. The group performed the experiment to identify the measurement of the objects or substances and also, to familiarize oneself to the units of measurements. The group computed for the weight and volume of the substances to be able to find the density which is the product of weight and volume. The group also computed for the relative error. It is the percentage of accuracy of the computed experimental value to the actual value. From the experiment performed, each members of the group learned how to find the measurements accurately and precisely. They also learned how to use the laboratory materials or equipment properly.
REVIEW OF RELATED LITERATURE
What are the concepts of density, volume and mass? This chapter aims to review theories on density, volume and mass. All of these are simple concepts, yet in order to work in chemistry or any of the other hard sciences, it is essential to understand these types of measurement (Advameg, 2012). Scientists define density as the mass of a substance per unit volume. The word “per” indicates that thinking about density requires thinking about a relationship. Its relation is between the mass (or weight) of one unit of a material and the volume of that one unit. Density cannot be directly perceived or measured. It is usually measured in kilograms per cubic meter. It must be inferred from the relationship of the mass and volume. To calculate density, first, find the weight and volume of an object precisely, then divide the mass...
