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 determine the density of an unknown liquid and an unknown solid density = mass units are: g or g where 1 ml = 1 cm3 volume ml cm3 to properly measure density, we need a container whose volume is known to a high degree of accuracy this container is known as a. Lab reports are an essential part of all laboratory courses and usually a significant part of your grade if your instructor gives you an outline for how to write a lab report, use that some instructors require the lab report be included in a lab notebook, while others will request a separate.
