Relative density

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

through the use of a diverse set of glassware: graduated cylinder, volumetric pipette, and burette. These unique measuring instruments played a role in concluding the densities of the two soft drinks, Coke and Diet Coke, and whether or not a statistical difference existed between the two substances. Conversely, the resulting densities determined by each of the differing glassware were assessed and compared to each other in terms of accuracy and precision, with the most precise tool that produced consistent

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

The purpose of this lab was to create an experiment to test samples of plastic-like cylinders, to see if the different masses had an effect on the density of the objects. The original hypothesis was if the mass of the substance increased there would be no effect on its density. As seen in the data analysis, the average density was 1.7 (g/mL), with only a negligible 0.1 (g/mL) difference across all four masses of the substance. Furthermore in the data, if the mass of the substance increased, the

how salt concentration and density affects floating objects. The control is water not having salt, and the constant variables are the amount of water in each cup and the objects. The independent variable is the amount of salt added in the cup. The dependent variable is the height of the water and the density of the water. Background Research How do objects float on water? The density and buoyancy are properties of matter that determine how objects float on water. Density shows the amount of mass in

presented were a cylinder, cube, and a rectangular prism. Through examining the physical properties of the objects the best possibility in finding the substance of each object was through finding the density. Density is defined by a physical property between the mass and the space taken up by the substance. Density is found by using the formula mass divided by volume. Identifying the mass and the volume of each object will help to identify if the objects are made of the same material. Through the initial

alcohol. 8. Calculate the densities of both the water and the isopropyl alcohol and record in Data Table 4. 9. The accepted value for the density of water is 1 g/mL and the accepted density for isopropyl alcohol is 0.786 g/mL. Determine the percent error between your calculated densities and the accepted values for both water and isopropyl alcohol. Record the percent error in Data Table 4.

vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3.

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola
