A property of a substance is a fact about the substance that may help identify it. Examples of properties are color,hardness and density. Density is the property that quantifies the comparisons of materials such as, \"lead is heavier than feathers\". In this lab you will take measurements on a sample of an unknown substance and calculate the density of that substance. Using this information, you will then identify the substance. You will need to find the substance that four different rods are made of based on density table provided below. How well did the density of your choice match your calculated densityfor each of your rods? If there was a difference, what might have caused it? How certain are you of your identification?

Given that you are reporting calculations for each rod document PROCESS for one rod and then show calculations only for others
