Mass Calculations

Calculation of Mass of Solids by dint of Calculation John Holmes teacher: Joe Blow October 23, 2010 enjoyment/INTRODUCTION The purpose of this try prohibited is to specify the mass of copper (Cu) and press (Fe) idles and a cognize quantity (1.1 g) of Sodium Chloride (NaCl) and in the treat expose weaknesses in measuring techniques and possible variations in measurements collectable to differences in equipment sensitiveness and standardization. In order to correctly determine the mass of the solids in question a methodology of compute measurement, disparateial measurement and calculation by averaging were implemented. In the conductivity of the experiment centigram remnant scales, electronic scales were utilized to measure and temper the mass of the bodily. In some cases the material was extend weighed on the scales and in otherwise cases the material was differentially weighed by placing the material in a beaker or watch ice rink therefore deliberation the beaker or watch glass and material unneurotic then(prenominal) weighing the beaker or watch glass unload and subtracting that weight from the combined weight of the beaker or watch glass and the material. record data shows that scales of the same type may award different readings primarily as a result of calibration error. As well differences in measured mass grass be attributed to the sensitivity and accuracy of the instruments used. Calculated average set were obtained by weighing multiple pigeon berrys of copper (Cu) simultaneously through the direct measurement method and dividing that measured value by the play of slugs being weighed. MATERIALS Materials required to conduct this laboratory experiment complicate: * Centigram Balance Scales (2 each) * Electronic Scale * High aesthesia Scale * look upon Glass * Beaker, 100 ml * Copper (Cu) Slugs (5 each) * Iron (Fe) angle (#1 from available lab samples) * Sodium Chloride (NaCl), 1.1g EXPERIMENTAL METHODS rea! lm One: Measure the mass of a copper (Cu) slug on two centigram...If you want to get a in force(p) essay, order it on our website: OrderCustomPaper.com
