Volume Three

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

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

substance. Furthermore in the data, if the mass of the substance increased, the volume increased proportionally with it. This information ultimately supports our hypothesis. As addressed during classroom lectures, the relationship between the two variables is most likely explained by the fact that density is a ratio. It would be logical to assume that while the mass and volume increase at the same rate, the division of mass by volume would result in nearly the same number.

used the most accurate and precise apparatus possible to ensure the results obtained were accurate. For measuring the gas volume, I used a gas syringe. A gas syringe is a special low friction syringe for measuring the volume of gas produced or to insert gas into a reaction. I chose to use the gas syringe as it is very appropriate and accurate, allowing me to measure the gas volume to an accuracy of 0.5 cm3. My choice in using the gas syringe as a measurement tool allowed me to ensure my results were

Indicates values for the concentration of the SDS solution made along with how it affected ∆P. The SDS concentration is in terms of weight by volume and the radius is calculated from the previous table. With the following information a plot can be formed and the graph that is formed that it allows for a polynomial graph to be present. Figure 3. The equation for the formula is y = -1.36E+09x3

the gas inside the container. What would be the volume of the gas? __.42 ______________ 7. Test: Test your prediction using the Gizmo. What is the volume of the gas? __.42___________ Was your prediction correct? ____yes_________ 8. Create a graph: Select the GRAPH tab. Set the mass slider to 0 kg, and click Record to plot a point on the graph. Plot a point for each possible mass to create a graph showing the relationship between pressure and volume. When your graph is completed, click the camera
