Courtney Verblaauw Dr. Reagor CE-101-02 February 26, 2010 Introduction Performed a number of experiments to test the differences between density and relationships of specific gravity between distilled water and sugar water. Background Density is a measure of how much mass is contained in a given unit volume (density = mass/volume). Specific gravity is the density of a substance relative to the density of water. For this experiment, we measured the weight of the beaker, add a certain volume of the water sample to the beaker, and then find the density of the sample. Experimental The first water sample was distilled water that had a mass of 19.4 grams and a volume of 20 mL.

Unformatted text preview: Its specific gravity was below. The second water sample had two packages of sugar added to it, which was stirred until dissolved. It had a mass of 22.2 grams, a volume of 20 mL, and its specific gravity was above. Results • Once the calculations were performed, sample no.1 had a smaller density than sample no.2. Sample Mass (grams) Volume (mL) Density (M/V) (gms/mL) Distilled Water 19.4 20 .97 Sugar Water 22.2 20 1.11 Conclusion • The sugar water had a larger mass than the regular distilled water, which resulted in the sugar water having a larger density. The density of fluid sample divided by the density of water is the Specific Gravity of that substance....
