DENSITY LAB REPORT Purpose: The purpose of this lab is to determine the effect that mass and volume have on density. Hypothesis: Write your hypothesis here BEFORE starting the lab. In this situation, it should relate to how mass and volume affect density. You should not attempt to guess the density of certain objects. Procedure: 1.

• Density – the degree of compactness of a material; defined as the ratio of mass to volume, often reported in terms of g/mL or g/cm 3 • Graduated Cylinder – a narrow cylinder with graduations to measure volume

Oct 4, 2024 · When determining the density of a pure liquid or a solution, the temperature of the sample must be measured. Why does the density of a liquid sample depend on the temperature? The density of the substance/sample varies as heat and temperature can change its density.
Density is the ratio of the mass of a substance to the volume occupied by the object: Density = mass volume The units of density varies, depending upon the substance measured. Density is grams per cubic centimeter (g/cm3) for solids, grams per milliliter (g/mL) for liquids, and grams per liter (g/L) for gases. The density of
Density is defined as the ratio of the mass of an object to the volume it occupies. Different materials can have different densities and density can be used to identify a substance.
Experiment #3. Density Goals 1. To measure and calculate the density of various substances. 2. To use significant figures correctly in calculations. Background Density is the mass per unit volume of a substance. If a substance has a lot of mass in small volume we would say it is dense.
Finding Density Using the measured masses and volumes calculate the densities of each object. Show the setup for one of for the four calculations in your lab journal. Record all of the results of the four calculations in a table. Table 5: Calculating Density Density of rock: Density of rubber stopper: Density of wooden block:
The purpose of this lab is to measure the density of various objects by using the water displacement method to determine volume and a scale to measure mass. Density is a key property that helps us understand how materials relate to each other in terms of compactness. What is your hypothesis (or hypotheses) for this experiment?
