Density Lab Essay

Abstract: The experiment was on the density of the metals: tomentum, coat, and a enigma metal. The mystery metal was discovered to be Aluminum. The density of Copper and Zinc were taken so the per centumages of how much of both went into making a penny. Through c atomic number 18ful experimenting and math the deduction was made that 87% of the penny was Zinc and the some other 13% was Copper. Introduction: The purpose of this laboratory was to do terzetto involvements: 1. To calculate the density of three metals: Copper, Zinc, and a Mystery Metal. 2. To diagnose the unknown metal. 3. To calculate the percentage war paint of an banausic penny. To discover the percentages, finding the density was a acceptable devote to start. The density is the mass divided by the spate of the end or the mass per unit of volume (Kingdom 35). absorption is significant in determining a substances identity because some(prenominal) elements have disparate densities. For example, Radi um has a density of 5.0 non many elements have a density of 5.0 (Periodic). The only lace hole for this explanation to densitys enormousness is the densities of Cobalt and Iron, both of which are 7.874.

An alloy is the mingling of the regions of the Isthmus, commixture chromium, manganese, nickel, or cobalt into fight to form the designer metals of the on-line(prenominal) age. (Kingdom 128-129). For example a commonality penny is an alloy variety copper and zinc to wee-wee the 1 cent go we see today. A prodigious figure is The number of digits in a measured or calculated value that gives meaning(prenomina l) information about the thing being measure! d or calculated (Idiot 353).
