the 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
learn 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
Abstract 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
determine 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
of this experiment is to find the density of metals through taking physical measurements and graphing data using the Vernier LoggerPro software. This was achieved through finding the mass and the volume of multiple samples of two types of metals and finding the average density of the samples of each type of metal, keeping record of the mass and volume of each sample, and inputting the data into the LoggerPro program. INTRODUCTION: Density is the mass per unit volume of a substance. It is the measure
composition. 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
comparing densities of sugar in soda to the density of sugar in solution of water. After the experiment it was found that the manufacturers measurements were accurate. Introduction The purpose of this lab was to determine if the information on the nutrition labels was correct for sugar. This lab could be used to find the content of sugar in and flat soft drink. Also companies may use a procedure very similar to find the percent of sugar
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
Title: Is there a correlation between the mass it takes to submerge 1cm^3 of a material and its density?

in the slug could affect the displacement method but it would not affect the calculation of volume by mass and length because the formula is not affected by changes in shape, just changes in measurement. There were outliers in the mass versus diameter graphs. 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
