In English 2111 we studied from the books of The Bedford Anthology of World Literature volume one through three. We as a class had to analyze three units; which were units 1 (Creation), 2 (Epic Heroes), and 3 (Courtly Love). Each unit had its level of difficulties but my favorite unit was unit 3 Courtly Love. Courtly Love gave me different outlook of love when I read the different poems and help me understand things I did not understand. To finish the summer strong we are to analyze once more taking
accurate and precise measurements while utilizing the correct volumetric containers that are used to quantify data. That way, all information that is collected can be trusted and accurately reflects the facts of the investigation. When measuring the volume of aqueous solutions, it is imperative to acknowledge the accuracy, precision, and percent error of the measurements. Accuracy is how close the results are to the actual accepted measurement, also known as the “true” value. Precision is how close

would be calculated to determine whether the objects are made of the same material. The objects are all different colors, sizes, textures and shapes. In order to find density, the mass and volume would need to be calculated. In order to calculate the density of an object two things must be calculated the mass and volume of the object.
made by a company manufacturing them will be assessed. This will be done by taking different volumes of water using a 10 mL graduated pipet, a 50 mL graduated buret, a 10 mL graduated cylinder, and a 50 mL graduated cylinder. After weighing each volume, we used the density of water at our room temperature to calculate the volume of each water samples. Then we compared that calculated volume (actual volume) to the one initially took; we used that result to assess the accuracy of our glassware by doing
small volumes. A micropipette is standard laboratory equipment used to measure and dispense a specific volume of liquid (#5 buffalostate.edu). This is a very helpful tool that we need to master and able to use in a biochemistry lab. The purpose of this lab exercise is learning how to use a micropipette to find the density of different liquids, and be able to identify an unknown liquid using density. Also, learn how to evaluate the experimental accuracy, precise, and error of small volumes used in
Contrasting Liquid Volumes to Determine Precision and Accuracy of Experimental Measurement Introduction The purpose of this experiment is to compare and contrast liquid volume reading values of different measuring devices, determining the precision and accuracy of experimental measurement. This was done through use of a graduated cylinder, a serological pipette, and a variable volume pipette. In laboratories, many kinds of containers and devices are available for measuring liquid volume. For example
found with the formula D=m/v. Which is defined as mass divided by volume to find the density. Procedure First, each metal’s description and weight was recorded. Additionally, the weights of each cylinder used was recorded. Next, a graduated cylinder was filled with 20mL of water and unknown metal II was fully submerged in the water 3 times. Each time, the volumes were recorded and the difference between the final volume and initial volume was calculated. This test was repeated for unknown metal IV.
the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml or g/cm³. This lab will focus on measurements. Mass and volume are physical properties that can be easily measured. In the lab, the mass was measured in grams and the volume was measured in ml. Limitations on results The percent error when
Together the mass of the water and the beaker is 47.8462g.the mass of the water is 19.0842g by using the equation of density equal mass over volume. Plugging the numbers in the equation with is 19.0842g divided by 19.9ml equals the density of water came out to be 0.959g/ml. The second experiment was the unknown substance. The unknown substance was salt water. The volume of liquid was 20.1 ml. the mass beaker
