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
(⁰C) - 73Cold water from tap (⁰C) - 15
Hypothesis on Salt Compared to Water: The salt solution will have a greater density than pure water as the substance mass is lager.
Some reasons for the water not boiling at 100⁰C could be: different temperature settings, not allowing enough time to fully boil and experimental error.
102⁰C-100⁰C 99.2-100
100⁰C 100
2-0.8
100⁰C 100⁰
0.02 X100%-0.008X100
=2=-0.8
C. Height= 3.6, Base=4.21, Width= 1.17
Volume = bXh/w
4.21X3.6/1.17 = 13.31
Density= mass/volume
21.3/13.31 = 1.6
Density= mass/volume
19.30=26.15/V
-26.15X19.30=V
-504.69=V
V=504.69
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.
