Lab report 11: archimedes principle, buoyant force 04/10/12 james allison section 20362 group 5 james allison, clint rowe, & william cochran objective: in this lab we will study the buoyant force we will study the supposed relationship between the amount of fluid displaced by an object and the amount of force that the displaced fluid pushes. Denisty & specific gravity lab 3 pre lab 3 study questions study play what property of oil makes it float on water the property of oil that allows it to float in water is it's density oil is less dense than water and dose not mix with water, allowing the oil to float on water water} 100 (g/ml) oil} 092 (g/ml) why would heating the gas in a hot. Lab informal report name:_____ penny density lab date:_____ the pre-lab is due before you conduct the experiment use the background information and procedure to help you complete the pre-lab. Density is defined as mass per unit volume and is expressed mathematically as d = m/v remember to show all calculation steps in your lab report 4 determine the temperature of the water to the tenths place use the handbook of chemistry and physics to find the density of water at this temperature 5 calculate the volume of. Lab report: the density of liquids and solids part a: the density of water experimental data st1 water addition 2nd water addition 3rd water addition mass of empty cylinder mass of cylinder + water mass of water only volume of water density of water average density of water. Copper penny lab report - measuring density extracts from this document introduction is it a copper penny measuring density experiment date: 30 september 2010 due date: 8 october 2010 is it a copper penny measuring density objective the objective of the experiment is to calculate the densities of pennies and determine the. 1 pre lab questions for week 1 chemistry of white wine: part a name:_____ you should have four questions on this pre-lab assignment. In this lab, you will determine the density of brass as measured by two different techniques: 1) volume calculation based on water displacement and 2) volume calculation using measurements of the radius and length of the cylinder using calipers mass and linear measurements are basic units in the metric system in chemistry, mass is.
Name: _____ pre-lab #1: introduction to lab techniques introduction to measurements there are numerous aspects to chemistry, but a common thread between them all is the process of. Lab activity – mass, volume and density identification of metal samples through density values purpose: in this experiment, you will • measure the mass and volume of known and unknown metal samples using a balance and the displacement method • use your raw data to calculate the density of the metal samples • compare your density. 1 density (reading assignment: chang, chemistry, 9th edition, pp 14-19) you may also receive pre-lab questions that must be answered prior to performing the experiment be sure that you bring your laboratory manual, a scientific calculator, and eye protection to each laboratory meeting failure to arrive on-time with each of these items is cause. General chemistry lab 1025c comparing the density of pennies-sl introduction: occasionally the us department of treasury changes the composition of pennies, which changes the overall mass and density of each coin in this experiment, you will determine the average density of two groups of pennies made at different times then.
Precision was found by taking the absolute value of the highest density minus the lowest density, dividing that difference by the average density, and then multiplying that answer by 1000 for example, the precision for the water was found by this equation: |(09958 g/ml – 09650 g/ml)| / 09823 g/ml x 1000 this gave me an answer of 313544 ppt. Pre-lab guidelines please follow the format provided below for your pre-lab write-up the pre-lab assignment is intended to prepare you for the lab and therefore should be written in your lab notebook before you come to the lab. Experiment 1 - density of liquids and solids goal: to accurately
