CHE 101
Experiment 1

Lab Techniques and Measurements

Purpose:
The purpose of this lab experiment is to review and learn the proper techniques for the measurement of length, mass and temperature. After this experiment I expect to have a better knowledge on how to correctly and efficiently measure for future lab experiments.

Data:
DATA TABLE #1

DATA TABLE#2-

DATA TABLE#3-

DATA TABLE #4

DATA TABLE #5

DATA TABLE #6

DATA TABLE #7

DATA TABLE #8

Data Table #9

Observation-
While performing the lab experiments in the first unit, my observation included finding the appropriate tools in the kit in order to carry out the tasks. These experiments really showed me how to differentiate the types of tools we are using and understand the differences and reason for the differences in each. Touch was a big activated sense in these experiments, the heat from boiling the water and the cold ice from the temperature labs allowed for the connection between the results and the way the temperature felt. Conclusion-

After performing each lab I have a much better understanding on what is expected and how to carry our future labs. I learned measuring techniques and although there is much room for improvement on my part, I think I have a good sense of what to expect and how to appropriately calculate my experimentations. The lab that I struggled with the most was the one represented in Table 9. I found the calculation of molarity to be a little confusing. I had a hard time producing results on this particular lab. I continued to redo it in attempt to get the correct calculations. I hope that I can take with me into future lab assignments the tools and know how to produce successful labs and results. Questions-

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?
