Laboratory Techniques & Measurements
Become familiar with several important laboratory techniques. Gain proficiency with some of the common measuring devices used in a chemistry laboratory. Determine the volume, mass, length, temperature, and density of objects and liquids
2. Temperature Measurements:
Cold water from tap (⁰C) – 15
Ice Water (⁰C) – 6
Ice Water after 5 mins. (⁰C) – 4
3. Volume Measurements:
4. Mass Measurements:
5. Density Measurements:
Hypothesis on Salt Compared to Water: The salt solution will have a greater density than pure water as the substance mass is lager.
6. Densities of Irregular Objects:
Cylinder + Object (mL)
Object Volume (mL)
Object Mass (g)
A. Some reasons for the water not boiling at 100⁰C could be: different temperature settings, not allowing enough time to fully boil and experimental error.
B. 102⁰C-100⁰C 99.2-100
C. Height= 3.6, Base=4.21, Width= 1.17
Volume = bXh/w
4.21X3.6/1.17 = 13.31
21.3/13.31 = 1.6
D. Density= mass/volume
Some new things that I learned from this lab are experimental errors can drastically effect the outcome and adding a substance such as salt to water will increase the density of water. I believe I did meet the lab objectives because in result of this lab I became familiar with lab techniques, gained experience using lab measuring devices and I learned the volume, mass, length temperature and density of some objects and liquids.
