Lab report. Since each lab group will turn in an electronic copy of the lab report, be sure to rename the lab report template file. In this lab, you extract and isolate DNA from strawberries using simple, household ingredients. For example, the density of a gold coin and a gold statue are the same, even though the gold statue consists of the greater quantity of gold. Day 2: Procedure for the preparation of aspirin ... Add 3.5 mL of acetic anhydride (density is 1.08 g/mL) using a pipettor (if you reset the pipettor to a different value, please reset it back to the 3.5 mL value so other students don't use the wrong amount). 10. Vers 2015-01-29 12 Experiment 1 INTRODUCTION TO THE ANALYTICAL BALANCE AND VOLUMETRIC GLASSWARE 2 lab periods Reading: Chapter 2, Quantitative Chemical Analysis, 7th or 8th Edition, Daniel C. Harris and CHEM 253 Quantitative Analysis Laboratory Experiments, 7th Edition, pg 4-11. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. Use the template provided to prepare your lab report for this experiment. Your report should include the following: Table(s) of raw data; Table(s) of results; Graph(s) Plot head in meters as y-axis against volumetric flow, in liters/min as x-axis. EXPERIMENTAL APPARATUS AND PROCEDURE ; Jaehyeok Jin, a graduate student in The Voth Group, has been selected for a William Rainey Harper Dissertation Fellowship for the 2021-22 academic year. Youâve probably learned or heard about DNA, but have you ever seen it? Objective Lab 1 - Density Determinations and Various Methods to Measure Volume Goal and Overview This lab provides an introduction to the concept and applications of density measurements. Calibration Fluid 8. 9.4.2 Identify your Unknowns Use the literature values in Table 2, the physical appearance and any other factors to Calculate the volume (in cm 3) of a cylinder with a measured height of 11.76 cm and a diameter of 7.22 cm. lab report lipid 1. experiment of lipiddr. From the point of view of the dynamics of the air, the important properties are its density and viscosity (think of Bernoulli's equation and the Reynolds number). The densities of brass and aluminum will be calculated from mass and volume measurements. The velocity of the fluid for both the orifice and venturi meters and can be seen in the Appendix section of this report. We usually record a lot more information in a laboratory notebook than we would report in a research paper. The bare minimum entries for an academic lab course, for each lab study, should include title of the lab study; introduction and objectives; detailed procedures and data (recorded in the lab itself); summary. Lab report for Experiment #2: Extraction Your Name: Name of TA: Lab Partnerâs Name: Lab Section: Title: Experiment #2: Extraction Observations: Weighed out 3.2568 grams of chemical mixture that was yellow in color. experiment date(s): 1 Experiment 1 - Density of Liquids and Solids Goal: To accurately determine the density of an unknown liquid and an unknown solid. (Concentrated reagent grade HCl has a density of 1.188 g mLâ1 and is 37 wt %. CHEM 139 Lab Guide Page 4 Experiment 9 9.4.3 Density Calculate the volume (in cm3) of each metal rod. CALIBRATION: First in this test we are calibrated the PH meter device by the standard water (PH=7). Swinburne has moved up in the QS World University Rankings 2022, placing 19th in Australia and 321 st globally. Probably the most common application in biology of this technique is in the measurement of the concentration of a compound in solution. The naming convention is as follows: [Table Number][Short Experiment Name].doc. Compare the theoretical value with the value you obtained in your experiment and comment on its accuracy. Summary. You should start the introduction by talking about what enzymes are and how they work. The ï¬rst will Check your answer with Apparatus of Experiment PH meter 6. Procedure 1) Calibrate the pH meter using the meterâs calibration function (follow the directions that come with the meter) using three pH standards. ð½=ð×ð×ð Use this volume and the mass of the rod to calculate density in g/cm3. You may handwrite this report, or use a word-processor. The report may be in ink or in pencil, and it may be written on plain paper or on notebook paper. 3. Plot hydraulic power in watts as y-axis against volumetric flow, in liters/min as x-axis. Since each lab group will turn in an electronic copy of the lab report, be sure to rename the lab report template file. Jar Test Lab Report - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. The naming convention is as follows: [Table Number][Short Experiment Name].doc. Density is a basic physical property of a homogeneous substance; it is an intensive property, which means it depends only on the substance's composition and does not vary with size or amount. 1: Equipotential Lines and Electric Fields Pre-Lab Questions Answer these questions on a separate sheet of paper and turn them in before the lab 1. Experiment 3 Introduction to Density INTRODUCTION The purpose of this experiment is to understand the meaning and significance of the density of a substance. In this experiment we will consider two objects. Isolation of Caffeine from Tea Leaves By: Julia Trimble. Before performing this experiment (i.e., in your prelab), calculate the volume of concentrated HCl you will need to prepare 250 mL of 0.1M HCl. A conclusion restates your goals and methods, includes any final data and notes whether you were able to successfully answer the questions posed by your experiment. There is no specific report format for this experiment. For example the group at lab table #5 working on the Ideal Gas Law experiment would rename their template file as "5 Gas Law.doc". If we have an object of mass m and volume V, its density Ï (the Greek lower case letter rho) is given by: Ï = m V (1) If the object is in a vacuum or, for our purposes, air, its weight, w, will be equal to mg, where g is the acceleration due to gravity. Theory Archimedesâ principle states that a body wholly or par- Experiment #3: Recrystallization Experiment Date: September 20, 2016 Lab Partners: Judienne Archer Tonja Bryant Alexis Dunn Objective: To separate benzoic and acetanilide impurities by the technique recrystallization and to calculate the percent recovery of benzoic ⦠; Voth Group Creates the first computational model of the entire virus responsible for COVID-19 When you are assigned a lengthy lab report, it is important to include a conclusion paragraph to sum up your procedures and results for your reader. 9. Dissolved dry chemicals in 38 ml CH 2 Cl 2 with gentle heating. Where Ï is the density of the fluid, V is the velocity, D is the diameter, and µ is the viscosity. Your report should include the following: Table (s) of raw data; Table (s) of results; Plots of the following graphs: Hydrostatic force (y-axis) vs depth of immersion (y-axis), Theoretical depth of center of pressure (y-axis) vs depth of immersion (x-axis),
