Volume Three

measurements and collect data to determine the physical properties of matter; density, volume, and mass. Materials: Graduated Cylinder Balance Water Unknown Liquid Paper Towels Weighing Paper Weighed Solid (Rubber stopper) Procedure: Part A Obtain a 10 ml graduated cylinder and measure its mass on the balance. Record. Pour water inside the graduated cylinder. In other to get the correct measurement of volume, read the bottom meniscus. Determine and record the mass of the graduated cylinder and…

In the volume lab, we found that the large graduated cylinder was the most accurate because it had less percent error when measuring the density of water over all of the other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the…

One of the most important activities of science is measurement. Measurement is a means of quantifying properties for identification. For example, density is the relationship between the mass and volume of a pure substance. One could determine if a piece of yellow metal is gold by determining its density. Measurement allows scientists to make comparisons. Measurement also provides a means by which scientists can judge the reproducibility of an experimental procedure. However, measurement is not…

1. a. My data demonstrated the law of conservation of mass in part 5 of the experiment, dissolving sugar in water. The law of conservation mass states that matter cannot be created or destroyed by can enter or leave the system. The system’s change in mass was 0.00 grams, resulting in support of this statement. The balance had an uncertainty of 0.05 grams. b. With this experiment, we had a closed environment within the vial, not allowing any particles to come in or out, further explaining why…

Objective- Our goal for this lab was to calculate the Density of a substance. We needed to make sure we had the materials to find mass and volume and then use a formula to calculate density. Introduction- The main principle of this experiment was to figure out the Density of certain objectives given to us in the lab. We had to know the the formula D-M/V in order to find the density of that object.We also needed to know the density of water(1.0 g/l) in order to predict if something would float…

flask. Once the mass was determined in grams, the density was easy to determine, by using the density equation. The second portion of this experiment was to calibrate a 10mL pipette. Once the density was determined for this section, the pipette volume could then be determined, regarding the amount. The data that was recorded in my lab notebook, from these five trials could determine the pipets calibration. I believe that the meaning behind this experiment was to carefully…

dioxide in the gas. Once the algae have consumed as much carbon dioxide as it can, it releases oxygen in the form of gas, which leaves the column through the opening in the top and returns to the atmosphere [7]. The three illustrations following the Bubble Column show the other three types of Vertical Column PBRs. Illustration "B" is an example of an "Internal Loop Airlift" PBR [7]. The "Internal Loop Airlift" PBR works similarly to the Bubble Column as the gas enters the column through the…

opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing the mass (g) by the density), the calculated density was then compared to a list of known densities to determine the liquid’s…

Maus is a two volume graphic novel written by Art Spiegelman. This intriguing work, which is the winner of the 1992 Pulitzer Prize, take us through the story of Art interviewing his father, Vladek, of his experiences from the Holocaust. Throughout the first volume, we can get an idea that for some unknown reason, Art has a feeling of guilt over him. As the book goes on, we can see that even though Art was not involved with the Holocaust in any way, the whole ordeal seems to have an affect on his…

“friend” profusely, there is a hint of arrogance in his words. To quote one of the letters, he said “[accept] them as the pure offering of childlike reverence, and graciously vouchsafe to regard with indulgence them and their youthful composer” (IMSLP Volume 1, Letter #1). It proven further when he was talking to a Dr. Schade about how his apology should be accepted and the reasons why. It seems that Beethoven was apologizing because he left…
