Finding Density Lab
Finding Density
Density is defined as mass per unit volume, which can be used to determine the object or
substance observed. Many people use the density of objects to find what it is and how to classify the
object. The object of the lab conducted was to find the density of the substances given and to find what
the unknown liquid and solid were. The process to finding what the unknown solid and liquid were,
was to find the density and to conduct multiple trials so when the density is discovered, it is possible to
compare the density found to another one in order to find the liquid or solid. Through finding the
density of objects and substances, it is possible to find what the subject is that is being searched due …show more content…
The density is calculated by finding the mass and volume then
dividing the volume by the mass. The found density is used to compare and for the unknown solid and
liquid is to make them known and find what they are. Finding the unknowns are done by calculating
their densities and finding what it is by comparing the density to other densities which can be found in
the chemistry text book. In finding the densities it is is possible to compare them to each other and find
the unknown densities of the experiment.
Hypothesis: If the volume of the substance is altered, then the mass will change also.
The independent variable in this case, is the volume because when the volume changes, it will also
change the mass, the dependent variable, which affects the density. That is why taking multiple trials is
convenient because by taking many trials it helps to understand how the different volume affects the
density and how density may change.

Once the mass was shown, the total mass was subtracted from the beaker mass, which had
been previously done. After the mass of water was measured, the beaker and graduated cylinder were
rinsed. The rinsing took place every time a liquid was used to measure the mass of. The second trial
was done according to the first but the volume was different, instead of 10 ml, 20 ml was measured.
The Copper cylinder was placed onto the electric balance, measuring the mass and the volume was
found by finding the radius and height then put into the equation, v=(pie)(radius squared)(height).
Following, the unknown solid was placed into a graduated cylinder with 10 ml so see the difference in
the measure the the volume could be conducted. Then the mass was conducted when the same amount
of the solid was placed on the electric balance, finding the mass. The same method was used for the
following trial but with more of the solid, instead of 1 ml, 2 ml were used. The densities were found by
dividing the found volume by the mass, this was done by all of the solids and liquids.
