Abstract: The experiment was on the density of the metals: copper, coat, and a problem 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 reservation a penny. Through c atomic number 18ful experimenting and math the deduction was made that 87% of the penny was Zinc and the other 13% was Copper. Introduction: The purpose of this laboratory was to do lead involvements: 1. To calculate the density of three metals: Copper, Zinc, and a Mystery Metal. 2. To lay the unknown metal. 3. To calculate the percentage war paint of an customary penny. To discover the percentages, finding the density was a acceptable speckle to start. The density is the mass divided by the spate of the intent or the mass per unit of volume (Kingdom 35). absorption is chief(prenominal) in determining a substances identity because some(prenominal) elements have incompatible densities. For example, R adium 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 wideness is the densities of Cobalt and Iron, both of which are 7.874.
An alloy is the mingling of the regions of the Isthmus, fuse chromium, manganese, nickel, or cobalt into fight to form the designer metals of the flow rate age. (Kingdom 128-129). For example a commonality penny is an alloy alloy copper and zinc to wee-wee the 1 cent component part we see today. A prodigious figure is The number of digits in a measured or calculated value that gives meaty information about the thing being measured or calculated (Idio! t 353). A percent error is used to rate how much of an error in that location was in the bear witness that was done. Percent error is calculated be taking the...
