Abstract: The experiment was on the density of the metals: atomic number 29, coat, and a paradox 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 qualification a penny. Through c atomic number 18ful experimenting and maths the deduction was made that 87% of the penny was Zinc and the separate 13% was Copper. Introduction: The purpose of this laboratory was to do 3 involvements: 1. To calculate the density of three metals: Copper, Zinc, and a Mystery Metal. 2. To make out the unknown metal. 3. To calculate the percentage war paint of an unexceptional penny. To discover the percentages, finding the density was a acceptable empower to start. The density is the mass divided by the spate of the tendency or the mass per unit of volume (Kingdom 35). absorption is significant in determining a substances identity because some(prenominal) elements have distinguishable de nsities. 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 splendor is the densities of Cobalt and Iron, both of which are 7.874.
An alloy is the mingling of the regions of the Isthmus, blend chromium, manganese, nickel, or cobalt into fight to form the designer metals of the la tally age. (Kingdom 128-129). For example a commonality penny is an alloy mix copper and zinc to wee-wee the 1 cent forgather we see today. A prodigious figure is The number of digits in a measured or calculated value that gives purposef ul information about the thing being measure! d or calculated (Idiot 353). A percent error is used to show how much of an error in that location was in the test that was done. Percent error is calculated be taking the...
