Purpose
The purpose of this lab is to learn how correctly use an analytical and top-loading balance, as well as finding the density using different glassware measurement tools. Aside from this another purpose is to learn about accuracy and precision in data.
Procedure
Please refer to Chemistry 1250 General Chemistry Laboratory Manual, Fall 2012-Summer 2013, Department of Chemistry, The Ohio State University, Hayden McNeil, Experiment , pages 5, for the proper procedure.

The slope of each mass/volume plot represents the continuous raising of the water’s mass based on the raising volume but a certain amount (in the plots case: every 5mL). The plot provides the measured density of water. The plot allows the person reading it to assume that for about each gram of water, there is about 1 mL of volume. A single measurement cannot confer all of the things the plot could. If in some occurrence there were a determinate error, the plot (or it’s points) would not follow the trend line and be inaccurate. Volume and Mass is being illustrated on the plot in an extensive way because Volumes and Mass both change based upon the amount of it’s counterpart. Density is being illustrated in an intensive way because it will remain the same regardless of the amount of Mass/Volume(unless there is none). There were no significant difficulties or errors that occurred with the experiment itself other than the possibly of measurements not being accurately taken.

Conclusion
The purpose of the experiment was to learn how to correctly use an analytical and top-loading balance, as well as find...

Laboratory Techniques and Measurements Essay

1675 words - 7 pages Purpose of Experiment: The purpose of this experiment will be to gain an understanding of the universal used system of measurements, known as the “International System of Units” or SI within a lab experiment. This system will then be used to measure temperatures, density and observe the nature of dilutions while using the M1 x V1 = M2 x V2 equation. The Archimedes Principle will be the standard for this experiment. Procedure: Read and

Evaluation- Like all experiments this experiment had human errors too for example while we took the result of the ammeter it changed, as in there was 1dp difference therefore I would count that as the only human error. Since it did not include a lot of difficult measurements there was no human error

2509 words - 11 pages experimental design is important in scientific research. How an experiment is designed and making it such that others can retest your hypothesis makes data more reliable as well as making it possible to find any errors in a scientific method. The way an experiment is conducted determines how valid and reliable the results are. If an experiment is not designed properly then the data collected would be invalid. Some examples would be, not
