Mass Calculations

Calculation of Mass of Solids by dint of Calculation John Holmes instructor: Joe Blow October 23, 2010 enjoyment/INTRODUCTION The purpose of this try bring out is to specify the mass of copper (Cu) and press (Fe) idles and a cognise quantity (1.1 g) of Sodium Chloride (NaCl) and in the treat expose weaknesses in step techniques and possible variations in measurements collectable to differences in equipment esthesia and standardization. In order to correctly determine the mass of the solids in question a methodology of compute measurement, oppositeial measurement and calculation by averaging were implemented. In the conductivity of the experiment centigram balance scales, electronic scales were utilized to measure and temper the mass of the bodily. In some cases the material was estimate weighed on the scales and in other(a) 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 wherefore weighing the beaker or watch glass unload and subtracting that heaviness from the combined weight of the beaker or watch glass and the material. preserve 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 swigs of copper (Cu) simultaneously through the direct measurement method and dividing that measured value by the chip of slu gs being weighed. MATERIALS Materials re! quired to conduct this laboratory experiment complicate: * Centigram Balance Scales (2 each) * Electronic Scale * High aesthesia Scale * endure Glass * Beaker, 100 ml * Copper (Cu) Slugs (5 each) * Iron (Fe) weight (#1 from available lab samples) * Sodium Chloride (NaCl), 1.1g EXPERIMENTAL METHODS approach 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
