Conclusion:
The purpose of this experiment was to learn about the international system of units, to become more familiar with common laboratory equipment and techniques, to gain proficiency in determining the volume, mass, lenth, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution. My conclusions from this was that I learned to be more accurate with my lab tools and became more familiar with the metric units of measurement, I was able to determine that the greater densities than water will sink as indicated by my results the...
