and Understanding Density‚ several experiments were performed to find density of regularly shaped objects‚ irregularly shaped objects‚ liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus

ACTIVITY 1 MEASUREMENTS IN SCIENCE: MASS‚ VOLUME‚ AND DENSITY Purpose: The purpose of this experiment is find the density of two metals using their mass and volume. Introduction: The purpose of the experiment that was conducted was to measure and calculate the density of two different metals. Density is an important characteristic of a material. The density of an object shows how much mass is contained in the unit volume. To calculate the density of metals the experimenters had to find out the mass

SCIENCE Density Calculate density‚ and identify substances using a density chart. Density is a measure of the amount of mass in a certain volume. This physical property is often used to identify and classify substances. It is usually expressed in grams per cubic centimeters‚ or g/cm3. The chart on the right lists the densities of some common materials. EQUATION: Densities of Substances Substance Density (g/cm3) Gold 19.3 Mercury 13.5 Lead mass density ϭ ᎏ volume

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

balance. Specific Gravity of each material are then calculated using the values obtained. Guide Questions: 1. Differentiate specific gravity and density. Specific gravity is the ratio of a material’s density with that of water at 4 °C where it is most dense and is taken to have the value 999.974 kg·m-3) and is therefore a relative quantity with no units. Density is defined as mass per unit volume; it has the SI unit kg·m-3 and is an absolute quantity. 2. If 54.96 mL of oil weighs 52.78g. What is

INTRODUCTION 1.1 Background of the Experiment Mass density describes how heavy an object is. Defined by the Greek letter ρ‚ read as rho‚ density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids‚ density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However‚ its CGS units‚ g/cm3 or g/ mL‚ are the most commonly used ones in the laboratory. The
