2. CALCULATIONS
a. Relative Percent Error = IAbsolute ErrorI/True Value X 100% IAbsolute ErrorI = ITrue Value - Measured ValueI
The Measured Value in my experiment based on table 2 is [(8.50+8.11+9.44)/3]= 8.68 g/cm^3 The True Value is 8.94 g/mL
Absolute Error = 8.94 - 8.68 = 0.26
Relative Percent Error = (0.26/8.94)x100=2.91 Using the correct number of significant figures, gives us the answer: 3%

b. Density of metal bar using dimensional analysis
D = Mass/Volume (g/cm^3)
V = LxWxH = 4.98x1.21x1.21 = 7.29
D = 70.5466g/7.29cm^3 = 9.68 g/cm^3

c. Density of metal bar using displacement of water
D = Mass/Volume (g/cm^3)
V = Volume of water level on graduated cylinder - Volume of the water dispensed from the buret V = 8.29 cm^3
D = 70.5467g/8.29cm^3 = 8.50 g/cm^3

3. RESULTS
"The relative percent error for the density of the metal bar by displacement of water on my experiment was 2.91%. Some possible sources of error that may have contributed to my percentage error could be related to mass...

...Experiment: determination of densities
Introduction
The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples, a unit volume means 1.0 ml. The units of density, therefore, are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter.
Density is often used as a point of...

Experiment 1: Determination of Density
Introduction
The purpose of this experiment was to be able to measure the density of water and an unknown substance with a buret and an analytical balance. The density can be calculated by dividing the mass per volume. It was expressed in grams per cubic centimeters, or in this case, grams per milliliters....

-Cylinder-Unknown Liquid
Procedure:
A. Density of liquids
Measure the mass of a graduated cylinder to the nearest 0.01g.
Add water to the cylinder, calculate the new mass of...

...6: Determination of Density
Abstract:
The purpose of the experiment was to determine if density is an intensive or extensive property of matter. The experiment proves that density is an intensive property. The density of an object remains the same no matter how much of it is present. The density is an intensive property because mass and volume changes at the same rate.
Introduction:
This experiment was...

...Experiment #2 “DensityDeterminations” Report
The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt, to see how density changes as a function of concentration.” In experiment #2, part II, calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased, so would the density,...

Purpose: To determine the densities of aluminum and zinc cylinders
Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size, the denser one may feel heavier. If their densities are close together, it can be hard to tell...

...LAB REPORT # 1
DENSITYDETERMINATION
CHEMISTRY 100 – 04
INTRODUCTION:
The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.
PROCEDURE:
1)...

... Report of DensityDeterminationsDensity is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment, we will determine the mass and volume of each object and then we will calculate the ratio—the density.
In the first part of the experiment, we...
