The density of fractions 1‚ 2‚ and 3 are as follows: 1.49‚ 1.325‚ and 1.34 g/mL. These values areincorrect because the density should not have been over 1.0 g/mL. This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing

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

Density of a given substance is independent of volume. Density never changes. I know that for a fact because during the “Density Does Not Change With Size” lab‚ we measured the length of rods given to us. For one I got 4.2cm‚ and when i weighed it on the scale I got 14.5g. Once I put the rod in the graduated cylinder I got 5.5cm squared. But when you divide your mass by volume‚ you will get your density. And for the density I got 2.6g/cm squared.Then for the other rod I got 6.7cm for length‚ 23.2g
