Density

MEASUREMENT OF DENSITY Lichang Wu Feb. 22, 2015 Abstract The purpose of the lab was to determine densities of materials. Density is the amount of matter in a given amount of space. Density is a physical property that is independent of the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml or

Discussion: Define and explain density in your own words. Density is calculated by dividing its mass by its volume (D=M/V). Density also describes how compact a substance is (amount of space occupied within a certain area). What is the difference between mass and density. The differences between mass and density are that mass is the amount of matter in an object and density is a measurement of how close the molecules are packed tightly together in a certain amount of space. In this lab, can

5861 Are these Objects Made of the Same Material? Every substance has its own unique density due to all of the atoms mass, size, and arrangement being different for each atom. Density is the relationship between two characteristics of matter which are mass and the occupied space. Density is a characteristic property, meaning the density of a substance will stay the same. In an investigation the objects densities would be calculated to determine whether the objects are made of the same material. The

Objective: My objective for this experiment is to find the mass, volume, and density of a variety of objects. After this, I will record my data and place a select few of the items on a graph. My hypothesis for this experiment is, "If I measure the mass of every object, the wooden ball will have the least because it seems to be the smallest and most lightweight. " 2. Equipment: 3 rubber stoppers, 5 rocks, wooden ball, wooden cube, 4 density cubes, triple beam balance, graduated cylinder, pipette, and beaker

Introduction a. The purpose of this density lab was to show the different ways density can be measured. Density is the measure of mass in matter. To find density, you would have to find the mass and the volume of the object. Then the mass would have to be divided by the volume to find the density. Density and specific gravity are similar because specific gravity is the density of a substance in comparison to the density of the standard. In this case, the standard is the density of water. The correct number

The purpose of this experiment is to learn how to measure mass and volume and to determine the density of water, alcohol, and a solid. We will be using a laboratory scale or balance and the graduated cylinder to determine the density of water and of alcohol. First, place an empty graduated cylinder on a balance, determine its mass and record the value under the Density of Water: Data Table. Next, pour 25 mL of tap water into the graduated cylinder. Place the cylinder on the lab bench and read the

Density: the compactness of a substance. That is the first thing that came to mind when I saw that diet coke floated in water and the cherry coke that sank in water. My group members and I measured the density of all three substances (diet coke, cherry coke, and water) and collected the data to see if density really was the cause. Based on our results, it turns out density really is the reasons diet floats and cherry sinks. After we collected our data from the lab, we did many calculations and found

In class we did a lab that helped displayed density. Density is the degree of compactness in a substance. To calculate a specific amount of density you will need to divide the mass by the volume and your quotient should be the density. In our investigation we were told to manipulate the density of the water using different amounts of salt to make an egg float, sink , and levitate, using various amount of trials. The materials we were given for this investigation was water, a beaker, and an egg

Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined, and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since
