Hamza Aziz General Chemistry I Lab 09/12/2007 Lab 7 Density of Sprite and Diet Sprite Abstract: The density of regular Sprite was found to be 1.037 +/- g/mL. compared to Diet Sprite which was 0.9965 +/- g/mL. Among the three volumetric glassware Pipette was most precise (ó=0.0016 g/mL). Burette was the second best (ó=0.0023 g/mL) and graduated cylinder was the least precise (ó= 0.007 g/mL). Density was found to be intensive property. The slope of the graph of mass against volume was 1.05

Density is how compact particles are inside an object. Objects can be different sizes but have the same density because the density depends on how close particles are together‚ not the size of an object. The density of water is 1 g/㎤. Any object with a density less than that will float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every

Experiment 1: Density | Purpose: To determine the density of the following liquids and solids. Data/Observation: Part A Sample | Distilled Water (g) | Methanol (g) | Glycerol (g) | Mass of empty cylinder | 41.1 g | 40.4 g | 41.1 g | Mass of cylinder + liquid | 51.2 g | 48.2 g | 53.8 g | Mass of liquid | 10.1 g | 7.8 g | 12.7 g | Calculations: Density of liquid = Mass/Volume = g/mL Distilled Water = 10.1g/10mL = 1.01 g/mL Methanol = 7.8g/10mL = 0.793 g/mL Glycerol = 12.7g/10mL

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different
