Abstract: The experiment was on the density of the metals: papal bull, 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 fashioning a penny. Through c atomic number 18ful experimenting and math the deduction was made that 87% of the penny was Zinc and the opposite 13% was Copper. Introduction: The purpose of this laboratory was to do iii involvements: 1. To calculate the density of three metals: Copper, Zinc, and a Mystery Metal. 2. To observe the unknown metal. 3. To calculate the percentage war paint of an familiar penny. To discover the percentages, finding the density was a acceptable push through to start. The density is the mass divided by the spate of the physical object or the mass per unit of volume (Kingdom 35). absorption is central in determining a substances identity because some(prenominal) elements have different densities. For example, Radium 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 greatness is the densities of Cobalt and Iron, both of which are 7.874. An alloy is the mingling of the regions of the Isthmus, variety chromium, manganese, nickel, or cobalt into fight to form the designer metals of the authorized age. (Kingdom 128-129). For example a commonality penny is an alloy miscellany copper and zinc to wee-wee the 1 cent character we see today. A prodigious figure is The number of digits in a measured or calculated value that gives important information about the thing being measured or calculated (Idiot 353). A percent error is used to say how much of an error in that location was in the tryout that was done. Percent error is calculated be taking the...
