Experiment 1.6: 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 designed to determine if density is an intensive or extensive property. The density of an object is found by dividing its mass by its volume. The volume of a regular shaped object can be measured with a ruler. The volume of an irregular shaped object can be measured by putting it in water and figuring out the displacement the object creates. An intensive property is a property that remains the same when the size of the sample is changed. An extensive property is a property that changes when the size changes. Hypothesis:

If the volume of a sample objects changes, then the density will stay the same because density is an intensive property. Materials and Methods:
The materials used in this experiment are an electronic balance, graduated cylinder, and paper clips. The electronic balance was compact scale that measured the mass in grams. The graduated cylinder was filled with water. The paper clips were an irregular shaped object. The mass of the paper clips was found using the electronic balance. The volume was found by measuring the displacement that was created by the paper clips.

Results:
The mass of 5 paper clips is 5.0 grams. Its volume is 1.0 milliliters. Its volume is 5g/mL. Although when more paper clips were added to the graduated cylinder, the density remained the same. This is because the mass also increased at the same ratio as the volume. Because of this the density of 9 and 13 paper clips is also 5g/mL. Number of Paper Clips| Mass(g)| Starting water volume (mL)| Ending Water Volume (mL)| Volume of Paper...

...of the 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...

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...

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...

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 %...
