Report of Density Determinations Density is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment‚ we will determine the mass and volume of each object and then we will calculate the ratio—the density. In the first part of the experiment‚ we should measure the density of some irregularly shaped chunks of rock. The Weight of rocks is 18.769g

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that compose them. We

equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data Table 8: Initial Concentration Chemical Mass (g)

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

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

Beverage Density Lab 1. Beverage Density Lab 2. Purpose: To find the different densities when there is a certain amount of sugar is added in water. 3. Materials: 1) A 100 mL beaker 2) Coconut Water 3) Powerade 4) Scale 5) Pipet 6) Sugar referred solutions (0%‚ 5%‚ 10%‚ 15% and 20%) 4. Procedure: 1) Get an empty 100 mL beaker and weight it on a scale. Make sure the sale is zeroed out. 2) Use the pipet and draw out 10.00 mL of 0% distilled water into the beaker. 3) Record

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
