I. Introduction

This experiment shows the relationship between density, mass, and volume. These three qualities are all related in that ρ = m/v, where p is density, m is mass, and v is volume. Through this experiment, however, it can be seen that by mixing certain substances, the density of the mixture can change, allowing certain goals to be met. In addition to this, finding density can be essential, as any substance has a density unique only to itself. For example, water (H2O) has a density of 1 g/mL, so any substance with that density has to be H2O.

This process investigated Archimedes’ principle, which deals with density. Archimedes states that “A body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid” (Archimedes’). This means that whether or not an object submerged in a liquid will float depends on the density of the object and liquid. If the object is denser than the liquid, it will sink; if the object is less dense than the liquid, it will float.

There are many ways to study this principle. For example, it could be tested in any fluid to see if Archimedes’ principle is still correct when dealing with gases; a heterogeneous mixture could replace the water to see demonstrate that it is truly density affecting the buoyancy of the object.

This method was used because it required only a simple procedure while still accurately displaying Archimedes’ principle. It also involved taking measurements and using significant figures, which is

## Does Height Affect The Density Of A Human Experiment

311 Words | 2 Pagesthe density of a human? We made three hypotheses to predict what would happen in the experiment.The null: Height doesn't affect density increased height results in increased density , decreased height results in decreased density. The primary goal was to see if height and density had any correlation. To do the experiment we measured the height and mass of the volunteers carefully, then measure the initial volume of water. Volunteers to enter the water slowly, measure and calculate the volume of each

## How Water Displacement Affected Density

881 Words | 4 Pageslearn how water displacement affected density. Another objective was to identify the metals used in our experiments. We used a variety of different metals to test their correlation and to find out if it was negative or positive. I did not expect to learn much from this experiment as we had already discussed density in class and learned that water displacement is basically volume so as it increased the density would have decreased had we used metals of the same mass. I will share my newfound knowledge

## Finding A Correlation Between A Solution 's Salt Concentration And Its Density

1154 Words | 5 PagesAbstract The purpose of this experiment is to find a correlation between a solution’s salt concentration and its density. The objectives are: First review use of electronic balance. Next learn to calibrate the glassware. Than learn to use a volumetric flask. After that learn how to determine density. Finally learn how to calculate percent error. It is known that density equals mass divided by volume which is a simple formula that gives half of the desired information. The equipment that was used

## Investigating Correlation Between A Solution Salt Concentration And Its Density

1135 Words | 5 Pagesdetermine the correlation between a solution’s salt concentration and its density. Also, it was to determine what equipment would be best to use to measure volume precisely and accurately. Densities of a series of known salt solutions were trialed three times and then averaged. By following the procedures, the unknown salt solution was determined and graphed to calculate the percent salt to the sample. Introduction In chemistry there are often times an unknown solution’s density must be determined

## Lab Report On Density

A number of studies such as Kitano,T have shown a strong correlation between skinfold and bioelectrical impedance analysis and tend to have an average body fat difference of less than 0.6. Body composition is a combination of numerous components these are: Fat mass, fat free mass, Adipose tissue mass, Lean body mass and relative body fat. Fat mass is defined as all the extractable lipids from adipose and other tissue. Fat free mass is all the left over chemicals and tissues, including water

The correlation coefficient would be closer to one if the highest and lowest measurement wsa omitted from the aluminum mass versus diameter graph. Mass and diameter do not correlate enough to justify an exlusion based on comparison of their physical
