Chem Lab Report

tightness Lab [pic] Gabby Zawadzki & Ola Tan on the wholeeri October 4, 2011 Period: H Gabby Zawadzki Density Lab I.Introduction      Throughout this lab there were several phases which came with their respective purposes.  Our offsetly objective was to determine the densities of chock ups of forest and aluminum.  Our next objective was to first calculate volume by measuring the dimensions of a unb annulable horseshit cylinder.   and so, after that we were to determine the tightfistedness of the same copper cylinder by using the volume found by the water displacement method.  Finally, we were attempting to identify three different extraterrestrial being liquids by parsimoniousness determinations.   cunning the density of a certain material gutter be very vital to a scientist because density is used in many different slipway in a chemistry lab.  Undoubtedly th e most big use of density is the skill to determine an foreigner substances identity. Since all material has a anomalous density a scientist can simply calculate the bundle and volume of an object, find the unknown objects density and he will, without a doubt, clear correctly identified the substance. II. observational Design      Procedure: Calculate the mass, length, width, and aggrandisement of both the woodland and aluminum clogs.  Record the banknotements in the selective information table. later on this is done, multiply each blocks length, width, and superlative microscope stage in revise to find the volume. Record your findings in the siemens table. Then create your density equation for each block (mass over volume) then calculate  and al-Quran the densities. Afterwards, locate the record hold dear density for wood and aluminum and record them. Then set up your percent error equation, which is contain value - experimental value over bo ok value, the account you end up with is yo! ur percent error. Record this number. After all of this is undefiled move on to Phase 2 of the lab.  First, measure the mass, diameter, radius, and vertex of your copper and unknown...If you want to get a rich essay, order it on our website: OrderEssay.net
